    摘要: A process of forming a polycarbonate comprises providing a reaction mixture of at least one polycarbonate-forming monomer and carbon dioxide; and then reacting the polycarbonate-forming monomer and carbon dioxide in the reaction mixture to form the polycarbonate. In one embodiment, the polycarbonate is present in a condensate, and the process further comprises removing carbon dioxide from the reaction mixture; and then collecting the condensate from the reaction mixture. Moreover, uncrystallized polycarbonate may be treated with carbon dioxide to form crystalline polycarbonate. The crystalline polycarbonate is then rendered useful for solid state polymerization.
