SYNTHESIS AND CHARACTERIZATION OF TELECHELIC LIQUID POLYMERS AND THEIR MULTIPHASE COPOLYMERS Ⅲ.SYNTHESIS AND DYNAMIC MECHANICAL PROPERTIES OF THREE-COMPONENT FOUR ARM STAR TELECHELIC COPOLYMER
【摘要】 本文在前报所合成的端羧基乙烯基四氢呋喃-环氧丙烷液体共聚醚的基础上,利用其端羧基同双官能团环氧反应,生成端环氧基三嵌段共聚物。然后再利用端乙烯基与烯类单体反应,制备了遥爪型三组份四臂星形共聚物。通过动态力学性能的测试,观察了一些因素对阻尼性能的影响。
【Abstract】 From carboxyl terminated vinyltetrahydrofuran-propylene oxide liquid copolymer(TVC), which has been successfully synthesized ealier (Ⅰ), we have synthesized anepoxy terminated triblock copolymer (TVCE) by reacting the terminal carboxyl of TVCwith bifunctional epoxy resin. The three-component four-arm star telechelic copolymerwas then prepared through the copolymerization of TVCE with vinyl monomers, e, g.St,MMA, and BA plus MMA. The effect of some factors on the dampling properties of star copolymers has beeninvestigated.
