NON-TECHNICAL:Many chemicals used in the plastics industry today are known to be toxic with adverse effects on human health and the environment. The objective of this SusChEM research project is to replace a well-known endocrine disrupting (ED) chemical used extensively in some plastics, coatings and adhesives called Bisphenol-A (BPA). BPA will be replaced with new biobased substitutes that will have the following important attributes: (a) Renewable Resources: Be synthesized using chemicals derived from renewable resources such as lignin, which is the world's most abundant renewable resource from trees and plants; (b) Properties: Have similar high performance properties to petroleum-based chemicals when used in such high volume applications as food containers, polycarbonates, composite resins and epoxy adhesives; (c) Toxicity: Have minimal impact on human health and the environment and have a low carbon-footprint; (d) Cost: Be produced in high volumes at low cost for the coatings, composites, automotive and renewable energy fields. This grand intellectual challenge will be tackled in a unique manner using a multidisciplinary approach which optimally integrates green chemistry, polymer science, structure-property relations, toxicity and renewable resources. TECHNICAL:The objective of this SusChEM research project is to replace a well-known endocrine disrupting (ED) monomer, Bisphenol-A (BPA), with a library of biobased substitutes such as Bisguaiacol-F (BGF) that will have the following important attributes: (a) Be synthesized using monomers from renewable resources such as guaiacol and vanillin from lignin; (b) Have similar thermal and mechanical properties to petroleum-based chemicals when used with co-monomers in high-performance polycarbonates, composite resins and adhesives; (c) Have low ED and environmental toxicity and (d) Be produced in high volumes at low cost for the coatings, composites, automotive food packaging and renewable energy fields. The project involves synthesis, polymer characterization, materials structure-properties, and computational and experimental toxicity studies. The greatest sustainability impact of this research will come from providing a non-toxic alternative to BPA from renewable resources that will both ensure future supplies of high-performance plastics and composites while bolstering the high volumes needed for the food packaging industry, renewable energy development in the wind turbine industry and the next generation of composite-based, fuel efficient, light-weight automobiles.

非技术性：众所周知，当今塑料工业中使用的许多化学品都有毒，会对人类健康和环境产生不利影响。 SusChEM 研究项目的目标是取代一种广泛用于某些塑料、涂料和粘合剂的众所周知的内分泌干扰 (ED) 化学品，即双酚 A (BPA)。 BPA 将被新的生物基替代品取代，该替代品将具有以下重要属性： (a) 可再生资源：使用源自可再生资源（如木质素）的化学品合成，木质素是世界上最丰富的来自树木和植物的可再生资源； (b) 特性：当用于食品容器、聚碳酸酯、复合树脂和环氧粘合剂等大批量应用时，具有与石油基化学品类似的高性能特性； (c) 毒性：对人类健康和环境影响最小，碳足迹较低； (d) 成本：以低成本大批量生产，用于涂料、复合材料、汽车和可再生能源领域。 这一巨大的智力挑战将以独特的方式利用多学科方法来解决，该方法将绿色化学、聚合物科学、结构-性能关系、毒性和可再生资源最佳地结合起来。技术：该 SusChEM 研究项目的目标是用双愈创木酚-F (BGF) 等生物基替代品库取代众所周知的内分泌干扰 (ED) 单体双酚-A (BPA)，该替代品将具有以下重要作用：属性： (a) 使用来自可再生资源的单体合成，例如来自木质素的愈创木酚和香草醛； (b) 当与高性能聚碳酸酯、复合树脂和粘合剂中的共聚单体一起使用时，具有与石油基化学品类似的热性能和机械性能； (c) 具有低 ED 和环境毒性； (d) 能够以低成本大批量生产，用于涂料、复合材料、汽车食品包装和可再生能源领域。该项目涉及合成、聚合物表征、材料结构性能以及计算和实验毒性研究。 这项研究对可持续发展的最大影响将来自于提供一种来自可再生资源的 BPA 无毒替代品，这将确保未来高性能塑料和复合材料的供应，同时支持食品包装行业、可再生能源开发的大量需求。风力涡轮机行业和下一代复合材料、节能、轻型汽车。
