Supported onium salts as initiators for the synthesis of polycarbonates by copolymerization of co2 with epoxides |
| abstract |
Supported onium salts used as initiators for the synthesis of polycarbonates by copolymerization of carbon dioxide with epoxides are described. Embodiments of the present disclosure describe initiators comprising an insoluble portion including an onium cation attached to an insoluble support; and an anion, wherein the anion is a counter-ion to the onium cation. Embodiments further describe methods of making polycarbonates using the initiator, methods of making initiators, and the like. |
