摘要

以二氧化硅为起始原料，与乙二醇、氢氧化钾反应，生成高活性的五配位硅钾化合物。以此为原料，与对苄氯苯乙烯反应，制得含双键官能团的四配位硅单体。然后与甲基丙烯酸β-羟乙酯进行自由基共聚合，得到含硅支链的共聚物。最后用IR、EA、EDS、TG、DSC、GPC 等对四配位硅单体及其共聚物作了结构表征。IR 表明，四配位硅单体在1630cm－1附近的C＝C 伸缩振动吸收峰在共聚物中消失。TG 表明，共聚物在343℃开始分解。分子链间通过羟基可以交联成体型结构，具有不溶不熔的特性。用DSC 测得共聚物的玻璃化温度为 48.1℃。

Abstract

High reactive penta-coordinated organic silicon was prepared via the reaction of silica with ethylene glycol and potassium hydroxide. Tetra-coordinated silicon monomer with a double bond was produced by the reaction of this penta-coordinated silicon with 4-vinylbenzyl chloride. Then the copolymer with silicon-containing branch was prepared. by the free radical polymerization of this tetra-coordinated silicon monomer with HEMA. The tetracoordinated silicon monomer and its copolymer were characterized by FTIR
