  • METHOD OF SYNTHESISING POLYCARBONATES IN THE PRESENCE OF A BIMETALLIC CATALYST AND A CHAIN TRANSFER AGENT
    Publication number: 20140249279
    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 polymerisation system for the copolymerisation 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 same. The invention also relates to novel catalysts of formula (III).
