The exclusive introduction of end groups into biobased aliphatic polyesters containing vinyl chain ends, prepared by ADMET polymerization of nonconjugated diene monomers, has been achieved by adopting olefin metathesis with a molybdenum-alkylidene catalyst followed by treatment with various aldehydes, and their quantitative introductions were confirmed by grafting PEG with certified values. The end-functionalized polyesters demonstrated unique emission and thermal properties through an interaction of the end groups; both melting and crystallization temperatures are affected by the end groups as well as the values.
通过采用钼亚烷基催化剂进行烯烃复分解反应，然后用各种醛进行处理，已实现将端基专门引入到由非共轭二烯单体通过ADMET聚合制备的含乙烯基链端的生物基脂肪族聚酯中，并且通过接枝具有认证值的聚乙二醇（PEG）证实了它们的定量引入。通过端基的相互作用，末端官能化聚酯表现出独特的发光和热性能；熔点和结晶温度均受端基以及（此处“the values”指代不明，推测有误，暂按字面翻译）值的影响。
