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