    摘要: In one aspect, the present disclosure encompasses polymerization systems for the copolymerization of CO2 and epoxides comprising 1) a catalyst including a metal coordination compound having a permanent ligand set and at least one ligand that is a polymerization initiator, and 2) a chain transfer agent having two or more sites that can initiate polymerization. In a second aspect, the present disclosure encompasses methods for the synthesis of polycarbonate polyols using the inventive polymerization systems. In a third aspect, the present disclosure encompasses polycarbonate polyol compositions characterized in that the polymer chains have a high percentage of —OH end groups and a high percentage of carbonate linkages. The compositions are further characterized in that they contain polymer chains having an embedded polyfunctional moiety linked to a plurality of individual polycarbonate chains.

    摘要: The present invention encompasses polymer compositions comprising aliphatic polycarbonate chains containing sites of olefinic unsaturation. In certain embodiments the aliphatic polycarbonate chains comprise sites of olefinic unsaturation capable of participating in radical-promoted olefin polymerizations. In certain embodiments, the invention encompasses composites formed by the polymerization or cross-linking of a combination of olefinic monomers and aliphatic polycarbonate chains containing sites of olefinic unsaturation.
