    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: This invention relates to a method for preparing compositions comprising terminally unsaturated polymers of low molecular weight, referred to as oligomers or macromonomers. In particular, a first oligomer composition is obtained by free radical polymerization of a reaction mixture comprising monomers. Terminally unsaturated oligomers in the first oligomer composition, or a selected portion of the composition, are reinitiated into free radicals in order to continue their oligomerization to a desired endpoint. The process is useful for preparing an oligomer composition having a controlled degree of polymerization. The process is also useful for preparing block copolymers. Such oligomer compositions or block polymers are useful for preparing engineered or structured polymers used in making various end products, including plastics, coatings, films, and dispersants.
