  • Method of synthesising polycarbonates in the presence of a bimetallic catalyst and a chain transfer agent
    Patent number: 9006347
    Abstract: 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).
