Synthesis Properties and Applications of CO2 Copolymers

CO2 is an important carbon resource developing at the end of this century. It has been possible now to readily copolymerize CO2 with epoxides to form aliphatic polycarbonates. By addition of third monomers,chain extenders and regulators,the chemical structure of the copolymers can be modified and the molecular weights and functionalities of the copolymers can be controlled. The polymerization processes can be simulated by computers with the knowledge of phase equilibrium in the system and the kinetics of the reaction. The properties of the copolymers can be modified and varied by chemical crosslinking, blending, complexation and IPNforming with other types of polymers. CO2 copolymers have found many applications and will certainly be an important polymeric material in the coming century.
