The effects of the composition of catalyst (the structure and amount of bident ligand and strong acid, the cocatalytic activity of Cu〓, the roles of methanol and phenol etc.) and the copolymerization condition (the reaction time, temperature, amount of ST and CO, the structure and amount of dilution reagent etc.) on catalytic activity were studied in detail. Also the optimum copolymerization condition was chosen.
