摘要
介绍了单体三氟丙基甲基环三硅氧烷通过硅氧烷醇锂催化剂聚合成氟硅生胶,讨论了不同催化剂及其用量,原料中水分含量、不同乙烯基含量对氟硅生胶分子量的影响。
Fluorosilicone gum was prepared by bulk anionic ring opening polymerization of 1,3,5- trimethyltris-1,3,5-（3,3,3-trifluoropropyl）-cyclotrisiloxane with lithium siloxanolate as catalyst. The influence of variety and dosage of catalyst, trace water and vinyl groups content over molecular weight was studied.
