摘要:Metallocene catalysts having plural coordination geometries for synthesis of high melting polyolefin copolymers suitable as thermoplastic elastomers. The inventive catalysts comprise unbridged, substituted or unsubstituted cyclopentadienyl metallocene catalysts that are capable of inter-converting between states with different polymerization or copolymerization characteristics, which interconversion is controlled by selecting the substituents of the cyclopentadienyl ligands so that the rate of interconversion of the two states is within several orders of magnitude of the rate of formation of a single polymer chain. Where r i >r f the polymer can be characterized as multiblock; where r i

摘要:The invention provides a process for the synthesis of a polycarbonate, the process comprising the step of reacting carbon dioxide with at least one epoxide in the presence of a catalyst of formula (I) and a chain transfer agent. The invention also provides a polymerization system for the copolymerization of carbon dioxide and at least one epoxide comprising a catalyst of formula (I) and a chain transfer agent, polycarbonates produced by the inventive process, a block copolymer comprising a polycarbonate produced by the inventive process, and a method of producing the block copolymer. The invention also relates to novel catalysts of formula (III).
