We have investigated the copolymerization of carbon dioxide and epoxide. In this paper, we wish to report that zinc N-methylated tetraphenylporphyrin catalyzed the alternating copolymerization of carbon dioxide and cyclohexene oxide. When zinc N-methylated tetraphenylporphyrin and cyclohexene oxide (500 equiv. with respect to the zn complex) in THF were heated (80°C, 3 days) under 50 atm of carbon dioxide with stirring in a autoclave, an alternating copolymer with average molecular weight of 60,000 was obtained in 98%. Moreover althernaiting copolymers with desired molecular weights were synthesized by changing the initial molar ration of cyclohexene oxide to the catalyst.
