METHOD FOR SELECTIVE PRODUCTION OF POLYESTER

摘要

PROBLEM TO BE SOLVED: To provide a technology for efficiently producing an alternating polyester copolymer under mild conditions in the reaction to polymerize propylene oxide and carbon monoxide in the presence of a transition metal complex. SOLUTION: The method for the selective production of a polyester comprises the polymerization of propylene oxide and carbon monoxide in the presence of a transition metal complex catalyst and an additive.
