面向本科生教学的开环聚合内容拓展

Extending Content of Ring-Opening Polymerization for Undergraduate Course

开环聚合作为与缩聚、加聚并列的第三大类聚合反应,具有如下特点:由于环状单体的特殊性,开环聚合反应无副产物生成;聚合物组成与单体的元素组成相同,即具有100%的原子利用率;大部分开环聚合反应具有连锁反应特征,链增长速度快;形成的聚合物链中含有杂原子,所得材料具有降解可控性。本文总结了近年来在开环聚合研究上的一些进展,如γ-丁内酯的开环聚合、活性开环聚合、易位开环聚合等,作为本科生《高分子化学》课程中"开环聚合"一章内容的有益补充。通过提供额外的一些参考文献来拓展本科生对前沿知识的了解,开阔优秀本科生的国际学术视野。

The ring-opening polymerization is an important method along the same as the step polymerization and the chain polymerization.There are many superior characteristics for the ring-opening polymerization such as no by-products during polymerizing process,100%atom utilization,high chain propagation rate,and controllable degradation/depolymerization.Here,the research progress of the ring-opening polymerization,including the successful ring-opening ofγ-butyrolactone,living ring-opening polymerization,metathesis ring-opening polymerization,etc,was summarized as a useful supplement to the chapter of"ring-opening polymerization"in the Polymer Chemistry Course for undergraduates.This paper can expand undergraduates’understanding of cutting-edge knowledge and widen the international academic horizon of outstanding undergraduates.Moreover,some additional references were listed as suggestions for further reading.
