While market demands have accelerated polyurea (PUA) development, achieving high-performance fire-resistant formulations remains a critical challenge. In this study, a novel core-shell hybrid flame-retardant particle, FPM@ZIF-67/ZIF-8, was successfully synthesized through the precise assembly of bimetallic ZIF onto functional polyphosphazene microspheres (FPM). By strategically incorporating biomass-derived resveratrol and phosphazene molecules to introduce flame-retardant features, such as phosphorus-nitrogen heterocycles and aromatic rings, and capitalizing on the synergistic interaction between these structures and the smoke-suppressing properties of ZIFs, highly efficient flame-retardant PUA composites were successfully prepared. Specifically, the 5 wt % FPM@ZIF-67/ZIF-8 composite achieves UL-94 V-0 rating with limiting oxygen index (LOI) increasing from 20.3 % to 28.4 %. Relative to pure PUA, reductions of 41.6 %, 40.9 %, and 37.8 % were observed in pHRR, THR, and TSP, respectively. Furthermore, robust interfacial adhesion between FPM@ZIF-67/ZIF-8 particles and the PUA matrix, combined with efficient energy dissipation mechanisms, resulted in enhanced tensile strength (20.8 MPa) and elongation at break (1014.6 %). This study advances the design of bio-derived core-shell flame-retardant hybrids, facilitating the creation of high-performance PUA elastomers with balanced fire resistance and mechanical integrity. These findings hold substantial implications for broadening PUA applications in fire-sensitive domains.</div></div>","PeriodicalId":406,"journal":{"name":"Polymer Degradation and Stability","volume":"241 ","pages":"Article 111536"},"PeriodicalIF":6.3,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604280","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}

This study has developed a method for functional and collaborative upgrading recycling of waste PET. By using chemical alcoholysis and copolymerization techniques, the waste PET is chemically modified into flame-retardant polyester polyols (rFR POL). It is then used as functional soft segments to polymerize, resulting in the synthesis of recycled high transparency, weather-resistant, and flame-retardant thermoplastic polyurethane (rFR TPU). Research shows using rFR POL as a soft segment cuts petroleum-based material use by 57 % in TPU production. And this enhances the transparency, hydrolysis resistance and flame retardancy of TPU films. After 14 days of hydrolysis and thermal weight loss tests, it was found that the molecular weight of rFR50 % TPU remains almost unchanged, with a high T_{5wt %} (225 °C). For rFR100 % TPU, the phosphorus content increases to 19,680 ppm, the LOI reaches 35.30 %, and the vertical burning is rated V-0. The flame retardancy mechanism is attributed to the synergistic gas phase and condensed phase flame retardant effects of P-N. The total GWP of this process is 2800 kg CO₂ equivalent, and the total cost is $1342 per ton, which is 37.8 % and 42 % lower than traditional petroleum-based TPU production, respectively. This process reduces polyester fire risks, fundamentally solves functional chain migration and excessive modifier issues. It also achieves upgraded recycling of non-biodegradable polyester, providing an innovative solution for green flame-retardant polymer development.</div></div>","PeriodicalId":406,"journal":{"name":"Polymer Degradation and Stability","volume":"241 ","pages":"Article 111537"},"PeriodicalIF":6.3,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604283","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}

With the increasing use of natural antioxidants like vitamin E (VE) in human-safety applications, whether their stabilizing effectiveness is affected by catalyst residues and whether traditional acid scavengers remain effective have become key issues requiring urgent resolution. This study systematically investigated the impact of hydrotalcite, a conventional acid scavenger, on VE's thermal stabilization performance in ZN polyethylene (ZN-PE). The results demonstrated that combining 500 ppm VE with 500 ppm hydrotalcite significantly extended the oxidation induction time of ZN-PE to 55.7 min at 190 °C, which surpassed the 30.7 min achieved by 1000 ppm VE alone. The changes in chemical structure, mechanical properties, and color of different samples after multiple extrusions and accelerated aging further confirmed the strong synergistic effect of VE and hydrotalcite in enhancing the thermal-oxidative stability of ZN-PE. Mechanistic investigations revealed that hydrotalcite primarily functioned by eliminating the impairment of VE’s antioxidant efficiency caused by the ZN catalyst. Additionally, hydrotalcite exhibited a certain adsorption effect on VE, which could control the release of VE, thereby extending its antioxidant efficiency in ZN-PE. These findings highlight the critical role of acid scavengers in optimizing VE performance, providing an effective strategy to optimize the use of natural antioxidants in ZN polyolefin stabilization.</div></div>","PeriodicalId":406,"journal":{"name":"Polymer Degradation and Stability","volume":"241 ","pages":"Article 111534"},"PeriodicalIF":6.3,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144587442","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}

A PE model containing antioxidants is aged in three different environments: deoxygenated water, oxygenated water and chlorinated seawater with oxygen. To elucidate slow-occurring phenomena, accelerated ageing experiments were performed across a range of chlorine concentrations and temperatures. Additionally, ageing tests are performed on samples of different thicknesses to distinguish between surface processes, reaction-based mechanisms and diffusion-involved mechanisms. In all cases, the loss of stabilizers is monitored by measuring the oxidation induction time. The results show that the physical extraction of stabilizers (leaching) can be described using existing theories from the literature, with the extraction constants identified based on tests in deoxygenated water at 60, 80 and 90 °C. It appears that the presence of oxygen in water leads to a faster decrease in stabilizers over time, explained by the reaction of these molecules with free radicals formed during the oxidation process. Kinetic rates associated with this process were determined at 40, 60, 80 and 90 °C. Finally, for the first time, the kinetics of stabilizer loss in chlorinated seawater are identified for two pro-oxidant concentrations at 21 °C.

Despite the multiplication of investigations aimed at developing new materials from these oligomers, there has been little interest in the prediction of their molecular weight after depolymerisation, even though it represents a major parameter influencing macromolecular properties; in fact, most studies only rely on a kinetic approach to obtain a targeted molar mass.
