A new strategy is presented for the synthesis of graft copolymers using only the ring-opening metathesis polymerization (ROMP). From a ROMP-derived main chain, pendant maleimide functional groups are converted into norbornene moieties via a Diels-Alder reaction with cyclopentadiene. The norbornene groups serve as sites of initiation, and subsequent ROMP from the main chain yields graft copolymers with both main and side chains derived from ROMP. This strategy offers ready access to defined graft copolymers.
提出了一种仅使用开环易位聚合（ROMP）合成接枝共聚物的新策略。从ROMP衍生的主链出发，通过与环戊二烯的狄尔斯-阿尔德反应，将侧链马来酰亚胺官能团转化为降冰片烯部分。降冰片烯基团作为引发位点，随后从主链进行的ROMP反应生成了主链和侧链均源自ROMP的接枝共聚物。该策略为合成特定的接枝共聚物提供了便利途径。
