This study investigates the functionalization of triethylene glycol dimethacrylate (TEGDMA) with (3-aminopropyl)triethoxysilane (APTES) via a Michael addition reaction. The primary objective is to monitor functionalization progress and quantify monomer conversion under varying conditions. The focus is on dental composite applications, where controlled functionalization is crucial for optimal polymerization. Additionally, the study aimed to establish a broader range of reaction conditions to achieve variable monomer conversion, beneficial for diverse applications. The study explored various silane-to-monomer ratios (1:4, 1:2, 1:1, 2:1) and reaction times (2 h to 7 days) to determine optimal conversion conditions. Two analytical techniques, NMR spectroscopy and size exclusion chromatography (SEC), are used to assess functionalization and conversion. While NMR provided structural confirmation and quantification, SEC proved efficient for both qualitative and quantitative monitoring. It differentiated between single and double functionalization and accurately estimated conversion degrees, and provided accurate conversion estimates, with conversion rates reaching up to 60%. The results demonstrate that SEC is highly effective for tracking the functionalization process, offering reliable data on conversion and reaction kinetics. These findings confirm that controlling silane-to-monomer ratios and reaction time allows precise tuning of functionalization degree, which is critical for optimizing polymer properties. These findings are essential for tailoring monomer functionalization for applications beyond dental composites. The results demonstrate that SEC offers a sensitive and rapid method to monitor functionalization kinetics, complementing traditional NMR analysis. This dual-analytical approach represents a novel strategy for precisely tailoring monomer functionalization, which can significantly reduce polymerization shrinkage in dental composites and has potential applicability in other polymer systems requiring controlled functionalization.</p>","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500217"},"PeriodicalIF":4.2,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, established recycling processes are not universally applicable. Pyrolysis can complement current recycling through the conversion of complex plastic wastes to condensates and gases for reintroduction into chemical industry processes. A multi-scale approach for the characterization of pyrolysis properties is presented using the example of polydicyclopentadiene. Pyrolysis-GC-MS (µg-scale), thermogravimetric (mg-scale), and lab-scale (g-scale) pyrolysis investigations are complemented by high-resolution product analytics. In Py-GC-MS, 1,3-cyclopentadiene is abundant, hinting at depolymerization as a dominant decomposition mechanism. In thermogravimetry, approx. 20 mass-% of the sample is converted to solids. On lab-scale, secondary reactions influence the product yield and spectrum significantly, indicated by a solid yield of ≈40 mass-%. Polydicyclopentadiene exhibits a broad product spectrum comprising unsaturated hydrocarbons and aromatics. In the condensed product, no 1,3-cyclopentadiene is detected, indicating recombination or derivatization reactions. Significant solid residue formation emphasizes scaling effects. The employed analytics provide comprehensive analyses of condensed and non-condensed products. With the presented approach, primary and secondary mechanisms can be resolved and crucial process parameters identified. In this way, a powerful toolset for the development of robust pyrolysis processes that aid in achieving circularity for plastics is provided.</p>","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500161"},"PeriodicalIF":4.2,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144179686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For designing advanced biomaterials with tailored properties to accelerate tissue repair, the stages of wound healing are introduced. The electrospinning of plant proteins is described, along with the modifications that enhance key properties such as mechanical strength and stability in wet environments. Their biodegradability makes them ideal for temporary applications, such as wound dressings and drug delivery systems, enabling the controlled and sustained release of antibacterial nanoparticles, antioxidants, and antibiotics. Moreover, the enhancement of skin regeneration by plant protein fibers is highlighted, focusing on their physicochemical properties, drug delivery capabilities, swelling behavior, and moisturizing effects.
