开环易位烯烃聚合物的动态交联改性研究进展
Progress in dynamically crosslinked polyolefins derived from ring-opening metathesis polymerization
摘要
Abstract
Ring-opening metathesis polymerization(ROMP)provides a precise and efficient way to prepare polyolefins,which enables the preparation of functional polymer materials with different topological structures.Although thermoplastic olefin polymers can be melted and reprocessed at high temperatures,their low mechanical properties and heat resistance limit their service life under extreme conditions.In general,the thermomechanical properties of polyolefin materials can be greatly improved by crosslinking modification,but it also brings difficulties to the recycling of waste materials.To address above limitations,fabricating dynamically crosslinked polyolefins with dynamic bonds has attracted extensive attentions.These polymers enhance mechanical properties while retaining the ability to be reprocessed.This review article focuses on the recent progress of polyolefins that are synthesized via ring-opening metathesis polymerization and followed by dynamically crosslinking modification.Finally,the development status and future research of this field are summarized.关键词
