采用以过渡金属Pd(Ⅱ )为活性中心的催化体系 ,催化苯乙烯 (St)及其衍生物对乙基苯乙烯 (ESt)与CO共聚合物反应。通过比较CO初始压力对催化活性的影响 ,探讨了不同共聚合体系的最佳条件。
Catalytic reaction of styrene (St) and its derivatives with ethyl styrene (ESt) and CO copolymer catalyzed by Pd (Ⅱ) as the active site. By comparing the effect of CO initial pressure on the catalytic activity, the optimum conditions of different copolymerization systems were discussed.
