High molecular weight polypropylene carbonates were prepared by CO2/propylene oxide copolymerization catalyzed by salcy‐naphthalene cobalt complexes. The introduction of methyl groups in the ortho position of naphthalene‐based salcy ligands and the catalyst loading in the presence of hexane as a co‐solvent were crucial to enhance the catalytic performance for the production of polycarbonates of high
通过水杨基萘钴配合物催化CO 2 /环氧丙烷共聚制备高分子量碳酸丙二酯。在萘基水杨基配位体的邻位引入甲基以及在己烷作为助溶剂存在下的催化剂负载量对于提高生产高分子量聚碳酸酯的催化性能至关重要。
