摘要

探索经过聚合-解聚过程的单体对于构建闭环化学回收系统具有重要意义。在本研究中，以1,5,7-三氮杂环[4.4.0]十二-5-烯为催化剂，证明了六元1,3-二氧杂环-2-硅环烷烃进行开环聚合。此外，单体再生通过聚合物降解是实现蒸馏结合反应与酸性催化剂。

Ring-opening polymerization of six-membered 1,3-dioxa-2-silacycloalkanes by an organobase catalyst: precision polymerization and monomer regeneration by polymer degradation

Exploring monomers that undergo polymerization–depolymerization processes is of great importance for constructing closed-loop chemical recycling systems. In this study, six-membered 1,3-dioxa-2-silacycloalkanes were demonstrated to undergo ring-opening polymerization with 1,5,7-triazabicyclo[4.4.0]dec-5-ene as a catalyst. Moreover, monomer regeneration via polymer degradation was achieved by a distillation-combined reaction with an acid catalyst.
