Abstract: Embodiments of the invention provide for methods of producing a composition comprising a crosslinkable silane-terminated polymer having at least one crosslinkable silyl group in each molecule. The method comprises providing a polymer having at least one unsaturated group and at least one alcoholic hydroxyl group in each molecule, adding to the 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 to form a composition comprising hydrosilylated polyoxyalkylene polymers, reacting the hydrosilylated polyoxyalkylene polymers with at least one isocyanate in the presence of a first tin-free catalyst to form an isocyanate reacted hydrosilylated polymer, and optionally reacting the isocyanate reacted hydrosilylated polymer with a polyol having a nominal functionality of at least 2 to form a polyol reacted crosslinkable silane-terminated polymer.

Abstract: Methods of producing a composition comprising a crosslinkable silane-terminated polymer having at least one cross-linkable silyl group in each molecule are provided. The method may comprise providing a polymer having at least one unsaturated group and at least one alcohol hydroxyl group in each molecule and having a number average molecular weight between about 100 and about 5,000, adding to the 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 to form a composition comprising hydrosilylated polymers, wherein the hydrosilylation reaction has a hydrosilylation efficiency greater than 50% as determined by 1H-NMR, capping the hydrosilylated polymers by adding the hydrosilylated polymer to at least one isocyanate at an index of between about 100 and about 250, and reacting the isocyanate capped hydrosilylated polymer with a polyol having a nominal functionality of at least 2 to form the composition comprising a crosslinkable silane-terminated polymer.
