COPOLYMERIZATION OF PROPYLENE OXIDE AND CARBON DIOXIDE WITHOUT PRODUCTION OF PROPYLENE CARBONATE

摘要

Copolymers of propylene oxide and carbon dioxide and homopolymers of propylene oxide are made using two dimensional double metal cyanide complexes having the formula Co[M(CN)₄] or hydrated or partially dehydrated form thereof. There is no propylene carbonate by product in the copolymerization.
