Abstract
Embodiments of the present disclosure describe a method of making a polycarbonate, comprising contacting one or more cyclic monomers and carbon dioxide in the presence of one or more of a Lewis acid catalyst, an initiator, and an ionic liquid; and agitating, sufficient to copolymerize the one or more cyclic monomers and carbon dioxide to create a polycarbonate. Embodiments of the present disclosure further describe a method of controlling a polymer composition, comprising contacting one or more cyclic monomers and carbon dioxide; adjusting an amount of one or more of a Lewis acid catalyst, an ionic liquid, and an initiator in the presence of the one or more cyclic monomers and carbon dioxide, sufficient to selectively modify a resulting polycarbonate; and agitating, sufficient to copolymerize the one or more cyclic monomers and carbon dioxide to create the polycarbonate.
