In this study, a universal monomer precursor toward N-acylated-1,4-oxazepan-7-ones (OxP)s was synthesized using a three-step approach, allowing for the introduction of various functional groups. Two novel oxidation sensitive OxP monomers bearing a double bond and a sulfide group were designed, as well as two monomers with alkyl moieties. The organocatalytic ROP of the OxP monomers using 1,8-diazabicyclo[5.4.0]undec-7-en (DBU) and 1 (3,5 bis(trifluoromethyl)phenyl)-3-cyclohexyl thiourea (TU) as catalysts was investigated. Polymerizations were performed under ambient temperature, affording homopolymers with narrow dispersities (Đ = 1.09–1.13). As a proof of concept, a post-polymerization thiol-ene functionalization of the allyl functional PAE was performed via photo-rheology experiments. Finally, the (bio)degradability of the N acylated poly(amino esters) was evaluated through a series of degradation studies under mild enzymatic catalysis, in neutral phosphate-buffered saline solution and under accelerated conditions.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":"10 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144547358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The escalating incidence of traumatic fractures, particularly accompanying accelerated demographic aging in numerous countries, has intensified the demand for effective treatment solutions. Clinically, mechanical fixation remains the most efficacious approach for fracture management, necessitating extensive utilization of rigid orthopedic devices including bone nails, plates, and splints. However, metallic internal fixation systems exhibit inherent limitations in biodegradability and lack of osteogenic promotion during bone healing. Moreover, these conventional methods prove insufficient for treating severe bone trauma such as comminuted fractures. To address these limitations, bone adhesives have been developed as innovative materials for comprehensive bone repair. Demonstrating liquid-phase adhesion capability at injury sites followed by solidification-induced stabilization, these systems offer significant advantages in operational convenience and therapeutic efficacy. This review systematically categorizes bone adhesives into three chemically and methodologically distinct classes: synthetic polymeric adhesives, natural biomatrix-based adhesives, and bio-inspired hybrid adhesives. Through structural analysis of chemical compositions and preparation protocols, we examine the correlation between functional groups and molecular architectures with clinical performance characteristics. Evaluations focus on identifying advantages and disadvantages in osteogenic potential, biocompatibility, and mechanical stability across material categories. By elucidating the structural rationale underlying successful clinical applications, this work aims to establish a foundational framework for guiding future adhesive development. The systematic analysis of material properties and functional mechanisms presented herein seeks to clarify developmental pathways and stimulate broader interdisciplinary research engagement in this field.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":"28 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144520912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In pulsed laser polymerization (PLP) kinetic studies, it is currently assumed that a MCR becomes a (fully developed) ECR after one propagation step. Here we demonstrate that a more gradual transition likely takes place, introducing a propagated mid-chain radical (PMR) with a propagation rate coefficient kp,P or equivalently a transition propagation factor γ that at least theoretically can very between 0 (kp,P=kp,m) and 1 (kp,P=kp,e). Kinetic Monte Carlo (kMC) simulations under free radical polymerization (FRP) conditions hint at a γ not too close to 0 (e.g. not below 0.01), and Density functional theory (DFT) calculations at a γ not too close to 1 (e.g. not above 0.8). It is further shown that the ratio of the peak heights in a PLP – size exclusion chromatography (PLP-SEC) spectrum is sensitive to a variation in γ. This opens the door to the future experimental determination of kp,P considering different frequencies, provided that the initiator radical generation is well-described. At 325 K and using 500 Hz literature data, we currently put forward a γ of 0.1. In addition, the PMR backbiting potential is evaluated, introducing a backbiting scaling factor ẟ with respect to the conventional ECR backbiting rate coefficient (kbb). It is showcased that this extra backbiting contributes to a better understanding of the migration mechanism and short branch formation in acrylate radical polymerization, although the experimental determination of ẟ is less straightforward. Overall the current work highlights how acrylate-specific rate coefficients can be obtained in a roadmap format, considering higher and lower frequencies, and lower and higher temperatures.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":"10 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144515558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, use of this technique has often been limited to custom built systems which can be difficult to reproduce and to use. In this work we present a guide to easily modifying commercially available high pressure liquid chromatography (HPLC)/GPC equipment, to facilitate their application as flow chemistry platforms with integrated online chromatography using commercial software for both instrument control and automatic analysis of multiple GPC traces. We demonstrate this approach as an entry point to conducting simple polymerization techniques using both batch and flow reactions with incorpo-rated automated online monitoring. The work outlined should enable wider adoption of techniques such as online-GPC for real-time monitor-ing of polymerization reactions which in turn leads to real time data available for both reaction process and product control.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":"24 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144515560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interestingly, an aggregation-caused quenching (ACQ)-to-AIE transformation is achieved during this SNPIE, where conjugated and ACQ curcumin transforms into nonconjugated and AIE polymer. This ACQ-to-AIE transformation might expand the library of AIE polymers, by taking advantage of widespread conjugated ACQ moieties. Further photocatalytic applications of obtained AIE polymer are carried out, which exhibits highly efficient activity with the optimal H2 production rate of 3122.5 µmol·g-1·h-1 under visible-light irradiation through a ligand‒metal charge transfer mechanism (LMCT) between curcumin-containing AIE polymer and titanium dioxide.

This manuscript presents a solvent-free melt polycondensation method using bio-sourceable urea with a combination of aliphatic and aromatic diamines, which bypasses isocyanate precursors. This approach allows direct incorporation of less nucleophilic aromatic diamines, previously challenging in earlier non-isocyanate routes. Adjusting the aromatic diamine content (5-20 wt.%) created polyureas with excellent thermal stability (Td,5% > 318 °C) and widely varied mechanical properties. Most notably, Young's moduli spanned three orders-of-magnitude (3 MPa to 1.1 GPa), from soft elastomers to high modulus thermoplastics. Although atomic force microscopy and X-ray scattering studies revealed amorphous morphologies without distinct nanoscale phase separation, ductile films exhibited excellent mechanical performance due to the presence of the urea functionalities, i.e., associative bidentate hydrogen bonding serving as physical crosslinks. This report demonstrates the efficacy of synthesizing high-performance semi-aromatic polyureas in the presence of an organocatalyst with tunable properties using greener synthetic methods without sacrificing material performance.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":"10 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144488840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
