METHOD FOR PRODUCING POLYCARBONATE POLYOLS BY THE IMMORTAL POLYMERIZATION OF CYCLIC CARBONATES
摘要
The invention relates to a process for the preparation of polycarbonate polyols, characterized in that cyclic carbonates are polymerized in the presence of DMC catalysts and chain-transfer agents consisting of polyether carbonate polyols.
