链转移剂在偏氟乙烯聚合中的应用进展

Application Progress of Chain Transfer Agents in Vinylidene Fluoride Polymerization

聚偏氟乙烯树脂具有优异的性能和可加工性,已成为继聚四氟乙烯之后消费量最大的含氟聚合物。链转移剂在聚偏氟乙烯树脂聚合过程中对控制反应速度、树脂的分子量和分子量分布有着重要的影响,本文介绍了不同链转移剂在聚偏氟乙烯聚合中的应用。

Polyvinylidene fluoride(PVDF) resin has excellent performance and processability,and has become the fluoropolymer with the largest consumption after polytetrafluoroethylene.Chain transfer agents play an important role in controlling the reaction rate,the molecular weight and molecular weight distribution of the resin in the polymerization of PVDF resin.This paper introduces the application of different chain transfer agents in the polymerization of PVDF resin.
