Abstract
Embodiments of the invention provide for a method of producing a silylated polyoxyalkylene polymer having at least one crosslinkable silyl group and at least one hydroxyl group in each molecule. The method comprises providing a polyoxyalkylene polymer having at least one unsaturated group and at least one alcoholic hydroxyl group in each molecule, wherein the polyoxyalkylene polymer includes an impurity double metal cyanide complex mixed therein, and wherein the polyoxyalkylene polymer has not been treated with a metal-coordinating compound; and adding to the polyoxyalkylene polymer a compound having a hydrogen-silicon bond and a crosslinkable silyl group in each molecule and a hydrosilylation catalyst to thereby carry out a hydrosilylation reaction, wherein the hydrosilyation reaction is performed in an absence of a metal-coordinating compound.
