Abstract
Most synthetic polymers are made from petroleum feedstocks. Given the nonβrenewable nature of these materials, there is increasing interest in developing routes to polymeric materials from renewable resources. In addition, there is a growing demand for biodegradable polymeric materials. Polycarbonates made from CO~2~ and epoxides have the potential to meet these goals. Since the discovery of catalysts for the copolymerization of CO~2~ and epoxides in the late 1960's by Inoue, a significant amount of research has been directed toward the development of catalysts of improved activity and selectivity. Reviewed here are wellβdefined catalysts for epoxideβCO~2~ copolymerization and related reactions.

A series of acid-base bifunctional catalysts (ABBCs) that contain one or two BrΓΈnsted acidic sites in the cationic part and a Lewis-basic site in the anionic part are used as efficient catalysts for the synthesis of cyclic carbonates by cycloaddition of CO(2) to epoxides, without the use of addition
