摘　　要：以甲基丙烯酸二甲基氨基乙酯、聚甲基氢硅氧烷为单体,在H2PtCl6催化作用下进行硅氢加成反应,合成氨基改性聚硅氧烷柔软剂,并对聚合物的结构进行IR表征分析。结果表明:两种单体聚合得到预期设想的聚合物,将柔软效果极好的氨基基团接枝到聚甲基氢硅氧烷的侧链上,反应路线简洁,且反应时间大为缩短。Amino-silicone softener was modified by the hydrosilylation reaction,with dimethylaminoethyl methacrylate and polymethylhydrosiloxane as the monomers,using H2PtCl6 as the catalyst.The copolymer was analyzed using IR spectroscopy.The results show that the polymer of two monomers formed is expected,the excellent soft amino group was grafted to the polymethylhydrosiloxane side chain,the reaction route was simplified and the reaction time is reduced greatly.
