Abstract

The use of Co ^III(salen)/Lewis base catalyst system for copolymerization of CO ₂ and propylene oxide was analyzed. The ratio of catalyst to Lewis base cocatalyst influenced the TOF. The use of Lewis base cocatalyst enables high catalytic activity at low CO ₂ pressure and affords superior enantioselectivity. The results show that the use of cocatalyst produced a highly alternating monodisperse polycarbonate product without concomitant cyclic carbonate production.
