摘要:A process offers a time-saving and cost-effective method for the continuous synthesis of terminally functional polymers through the use of efficient termination reagents from the group encompassing oxiranes, sulphur-containing oxirane analogues and nitrogen-containing oxirane analogues. The continuous process allows the introduction of different functional groups. Within a relatively short time, the properties of the polymers, such as general chemical composition, molecular weight, polydispersity, chemical composition and functionalization of the chain end, and chemical composition of the end groups, can be varied within a wide range. The polymers obtained in accordance with the invention are particularly suitable as a dispersion reagent for the mixing or stabilization of two materials which differ in mixing behaviour. Coating materials are a further possible application, for the adjustment of surface properties or the adaptation of rheological properties of viscous materials.

摘要:A new and efficient method of functionalizing high molecular weight polymers through alkylation using a metal hetero alkylbase is described. This novel procedure can also be used to synthesize polymer-based macro-initiators containing radical initiating groups at the chain-ends for synthesis of block copolymers.

摘要:In one aspect, the present disclosure encompasses polymerization systems for the copolymerization of CO 2 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 one or more sites capable of initiating copolymerization of epoxides and CO 2 , wherein the chain transfer agent contains one or more masked hydroxyl groups. 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, a high percentage of carbonate linkages, and substantially all polycarbonate chains having hydroxyl end groups have no embedded chain transfer agent.

摘要:The present invention provides methods for reducing induction periods in epoxide-CO 2 copolymerizations. In certain embodiments, the methods include the step of contacting an epoxide with CO 2 in the presence of two catalysts: an epoxide hydrolysis catalyst and an epoxide CO 2 copolymerization catalyst. In another aspect, the invention provides catalyst compositions comprising a mixture of an epoxide hydrolysis catalyst and an epoxide CO 2 copolymerization catalyst.
