The bioproduction of betulin (cycloaliphatic diol) using engineered baker's yeast (<em>Saccharomyces cerevisiae)</em> has been demonstrated from a model carbon source for plastic waste. Sustainable TPUs were synthesized in a two-step route with betulin as a chain extender (in different amounts), and with methylene diphenyl diisocyanate as an aromatic diisocyanate and different poly(tetrahydrofuran) (PTHF), as a sustainable long polyol, with varying molar masses. A specific study of betulin hydroxyl (OH) groups have been developed. To the best of our knowledge, such reactivities study had never been studied. It clearly shows the lower reactivity of the secondary OH group and the importance of temperature and catalyst content control on the urethane bond formation. The different obtained sustainable TPUs exhibited high thermal stability due to the specific betulin cycloaliphatic structure. TPUs with only high molar masses PTHF have achieved good phase segregation and elastomeric behavior. The sufficient distance among hard segments allowed interactions between them, reducing the affinity between hard and soft segments, with a specific organization based on phase separation. These TPUs offered adequate thermo-mechanical properties and processability, with stiffness and high Young’s modulus, for a large range of potential applications. Taking into account their architectures, the end of life of these sustainable thermoplastics is largely open to physical or chemical recycling approaches.</div></div>","PeriodicalId":315,"journal":{"name":"European Polymer Journal","volume":"230 ","pages":"Article 113909"},"PeriodicalIF":5.8,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional FRC manufacturing methods rely on thermal curing, which involves high energy consumption (often exceeding 100 °C for several hours) and long processing times, increasing production costs and limiting sustainability. To address these limitations, light-induced polymerization has emerged as a promising alternative. Light-induced polymerization, a process in which monomers are transformed into polymers through photoinitiators, offers spatial and temporal control, significantly reducing curing times to minutes while minimizing energy consumption. Unlike thermal curing, this method enables precise polymerization using various wavelengths of light, from UV to visible range, while reducing the need for toxic chemicals or solvents. Studies have demonstrated that UV-cured FRCs can achieve mechanical properties comparable to thermally cured composites, depending on the fiber content and resin formulation. Recent advancements, such as stepwise UV curing and radical-induced cationic frontal polymerization (RICFP), have improved light penetration, enabling uniform polymerization even in thick laminates (up to 20 mm). However, challenges such as limited light penetration due to fiber absorption and optical interference remain key barriers to widespread adoption. This review uniquely consolidates recent advancements in light-induced polymerization for FRC fabrication and critically evaluates strategies to overcome these challenges, including photoinitiator selection, diluent optimization, and wavelength tuning. By systematically discussing the role of photoinitiators, fiber types, fillers, and irradiation wavelengths, this work provides novel insights into the chemistry, processing strategies, and future directions of this emerging technology.</div></div>","PeriodicalId":315,"journal":{"name":"European Polymer Journal","volume":"230 ","pages":"Article 113902"},"PeriodicalIF":5.8,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680120","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}
