摘要
合成并表征了一种新型高效的席夫碱钴催化剂,其用于催化二氧化碳与环氧丙烷的聚合,得到了窄相对分子质量分布的聚碳酸酯.另外,系统地探讨了其在不同反应温度,CO2压力,反应时间及催化剂用量下对催化二氧化碳与环氧丙烷共聚的催化影响,得到了聚合反应的最佳条件.
A novel and efficient Salen-Co Cl catalyst has been synthesized and characterized,which was used to catalyze the polymerization of carbon dioxide and propylene oxide,and leading to the polycarbonate with narrow molecular weight distribution. In addition,the catalytic effect on copolymerization of carbon dioxide and propylene oxide under different reaction temperature, CO_2 pressure,reaction time and catalyst dosage have been systematically investigated,and the optimum conditions for polymerization were obtained.
