Conventional protective approaches, however, often involve adding antioxidants during processing, which not only causes significant environmental pollution but also limits the applicability of rubber products in the biomedical field. Therefore, developing robust aging mitigation strategies constitutes a critical imperative to ensure material longevity. This study proposes a feasible and effective strategy: inducing network rearrangement in rubber through pre-stretching to achieve a more stable crosslinked structure, thereby enhancing its thermo-oxidative stability. During vulcanization, polysulfide and disulfide bonds are formed in the crosslinking network of rubber. Pre-stretching preferentially broke weaker bonds, inducing the conversion of polysulfide bonds to disulfide bonds during the stretching process. This strain-induced network rearrangement enhanced the rigidity and stability of rubber. At elevated temperatures, this mechanism became more pronounced. Pre-stretching triggered rapid conversion of polysulfide to disulfide bonds during the initial stages of thermo-oxidative aging. Given the higher bond energy and stability of disulfide bonds under thermal-oxidative conditions, the aging resistance of rubber is significantly improved. Both atomic force microscopy tests and mechanical tests demonstrated that stretching induced dynamic transformation of sulfur bonds in the crosslinking network, leading to significant changes in spatial heterogeneity under thermo-oxidative conditions. As a result, the thermo-oxidative resistance of natural rubber was enhanced, with the retention of tensile strength increasing from 58.6 % to 81.1 % after 24 h of thermo-oxidative aging. This study not only provided important guidance for the general design of thermo-oxidation-resistant elastomers but also advanced the understanding of rubber network evolution mechanisms under thermo-mechanical coupling conditions.</div></div>","PeriodicalId":20916,"journal":{"name":"Reactive & Functional Polymers","volume":"216 ","pages":"Article 106415"},"PeriodicalIF":4.5,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144695217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a novel, metal-free nitrogen-rich organic polymer, CMBr-OP, designed as an efficient catalyst for the cycloaddition of CO<sub>2</sub> with epoxides to produce cyclic carbonates. Synthesized through a straightforward one-step polymerization of cyanuric chloride and melamine, followed by functionalization with bromoacetic acid, CMBr-OP integrates multiple active sites, including nitrogen-rich triazine units and bromine functionalities, which synergistically enhance catalytic performance. Under mild reaction conditions (110°C, 1 MPa CO<sub>2</sub> pressure, 6 h), CMBr-OP achieves an impressive 99.6% yield of chloropropene carbonate without requiring co-catalysts or solvents. Comprehensive characterization techniques, including FTIR, XPS, SEM, and BET analysis, confirm its hierarchical porous structure, high surface area, and uniform distribution of active sites, facilitating efficient CO<sub>2</sub> activation and epoxide ring-opening. The catalyst demonstrates remarkable versatility, effectively catalyzing a wide range of epoxides, and exhibits excellent recyclability, maintaining high activity over five consecutive reaction cycles. DFT calculations reveal the critical role of hydrogen bond donors, nitrogen sites, and bromide ions in activating both epoxides and CO<sub>2</sub>, underscoring the cooperative synergy within CMBr-OP. This work represents a significant advancement in sustainable catalytic systems for CO<sub>2</sub> utilization, aligning with green chemistry principles and offering a promising candidate for industrial-scale applications aimed at reducing CO<sub>2</sub> emissions and promoting environmentally friendly chemical processes.</div></div>","PeriodicalId":20916,"journal":{"name":"Reactive & Functional Polymers","volume":"216 ","pages":"Article 106412"},"PeriodicalIF":4.5,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144695215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
