【摘要】 以丙烯酸高碳醇酯、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,合成长链烃基改性硅油,通过正交实验探讨了相关因素对硅氢加成反应转化率的影响。利用IR和1H-NMR对聚合物的结构进行表征分析,结果表明:两种单体之间的硅氢加成反应得到预期设想的聚合物,获得β-1,2-加成产物。更多还原

【Abstract】 Long chain alcohol acrylate was grafted to polymethylhydrosiloxane bone by hydrosilylation,with hexachloroplatini acid as catalyst.Through orthogonal experiment,main factors affecting the graft reaction between LCAA and PMHS were discussed.FTIR and 1H-NMR spectra indicated that the hydrosilylation reaction followed the Markovnikov’s rule and played a strong preference toward β-1,2-addition.更多还原
