C08G 18/71

US Classification:

528 67, 528 75, 556444

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.

International Classification:

C08G 18/38

US Classification:

524590, 525460

Abstract:

Embodiment of the invention provide for compositions having at least one crosslinkable silyl group in each molecule. The crosslinkable silane-terminated polymer may include a reaction product of at least a polyol having a nominal functionality of at least 2 and a isocyanate capped hydrosilylated polymer. The isocyanate capped hydrosilylated polymer may include a reaction product of at least one isocyanate and a hydrosilylated polymer. The hydrosilylated polymer may include a reaction product of a the reaction of at least a) a polymer having at least one unsaturated group and at least one alcoholic hydroxyl group in each molecule and having a number average molecular weight of between about 100 and about 5000 and b) a compound having a hydrogen-silicon bond and a crosslinkable silyl group in each molecule.
