加成型硅橡胶铂催化剂的制备及其活性研究

Preparation of platinum catalysts for addition siicone rubber and their catalysis activity

合成了几种不同的铂催化剂 (氯铂酸二乙烯基四甲基二硅氧烷 ,氯铂酸 -异丙醇 ,氯铂酸 -邻苯二甲酸二乙酯 )。考察了其对于有机硅橡胶加成聚合反应的催化活性 。

Three kinds of catalyst (chloroplatinic acid isopropanol, chloroplatinic acid M Vi M Vi , chliroplatinic acid diethyl o phthalate) are synthesized. Among these three kinds of catalyst, chloroplatinic acid M Vi M Vi has the highest activity and chloroplatinic acid isopropanol has the lowest activity, chloroplatinic acid diethyl o phthalate's activity is ranged between the above two kinds of catalyst. The reason that the catalyst has different activity is discussed by catalysis mechanism.
