METHOD FOR PRODUCING HYDROLYZABLE SILICON GROUP-CONTAINING OXYALKYLENE POLYMER AND CURING COMPOSITION THEREOF

摘要

Disclosed is a method for efficiently producing 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 a hydrolyzable silicon group-containing oxyalkylene polymer which is characterized in that 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 is used as the raw material and the active hydrogen groups are converted into hydrolyzable silicon groups.
