摘要
利用乙酸钯和２，２′－联吡啶组成的催化剂体系催化一氧化碳和苯乙烯交替共聚制备聚（１－氧代－２－苯基丙撑），考察了组成催化剂的２，２′－联吡啶和对甲苯磺酸与钯（Ⅱ）的摩尔比对催化活性的影响，同时考察了甲醇用量、溶剂。
Carbon monoxide and styrene alternating copolymerpoly (1 oxo 2 phenyltrimethylene) was prepared using a catalyst prepared from palladium acetate and 2,2′ bipyridyl. The effect of molar ratios of 2,2′ bipyridyl, p toluenesulfonic acid and palladium(Ⅱ) on catalytic activity was studied, and the influence of methanol, solvent, reaction temperature and time on the reaction was also investigated.
