LOW VISCOSITY SILYL-MODIFIED POLYMERS

摘要

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.
