Abstract

The present invention provides a method of carrying out the cationic polymerization of a monomer in carbon dioxide. The method includes the steps of (a) providing a reaction mixture comprising carbon dioxide, a monomer, a catalyst and a cationic polymerization initiator, wherein the cationic polymerization initiator is capable of initiating the cationic polymerization of the monomer; (b) polymerizing the monomer in the reaction mixture to form a polymer.
