摘　　要：以端氢硅油(PHMS)和1,6-己二醇二丙烯酸酯(HDDA)为原料在铂催化剂的作用下,用硅氢加成反应合成了两端带有双键的紫外光固化有机硅。采用红外光谱内标法测定了端氢硅油中活泼氢的转化率,讨论了反应温度、反应时间、反应物质的量比等因素对转化率的影响。确定了最佳反应条件:反应温度为90℃、反应时间为4h、1,6-己二醇二丙烯酸酯与端氢硅油的物质的量比为1.4∶1.0。The poly（methyl silicone） for UV curing with side group of C=C was prepared by hydrosilylation reaction of poly（methylhydrosiloxane） （PHMS） and 1,6-hexanediol diacrylate （HDDA） in toluene using isopropanol solution of H2 PtCl5 as a catalyzer. The conversion yield of the reaction was determined by internal standard method of FTIR. The effect of reaction temperature, reaction time, molar ratio of HDDA to PHMS on the conversion yield were discussed. The optimal reaction process was acquired： reaction temperature was 90℃, reaction time was 4h, and molar ratio of the HDDA to PHMS was 1.4 ： 1.0.
