Abstract
Abstract A process for producing an unsaturated group-terminated polyalkylene oxide, which comprises subjecting a monoepoxide having at least 3 carbon atoms to ring-opening addition polymerization to an initiator in the presence of a double metal cyanide complex catalyst, followed by converting terminal hydroxyl groups of the resulting hydroxyl group-terminated polyalkylene oxide to unsaturated groups.
