METHOD FOR PRODUCING OXYALKYLENE POLYMER

摘要

Disclosed is a method for efficiently producing an oxyalkylene polymer having an active hydrogen group. This oxyalkylene polymer serves as a raw material for a hydrolyzable silicon group-containing oxyalkylene polymer which has a low viscosity while securing flexibility of a cured product, causes no contamination around a sealed portion, and has no adverse effect on adhesiveness. Specifically disclosed is a method for producing an oxyalkylene polymer wherein a first oxyalkylene polymer having at least two active hydrogen groups and a second oxyalkylene polymer having one active hydrogen group exist together, in which method an alkylene oxide is reacted using a first initiator having at least two active hydrogen groups and a second initiator having one active hydrogen group in the presence of a catalyst.
