Patent ID: 7307134

Claim:
A method of making an alkoxysilyl endcapped polymer, comprising the steps of: reacting a first reactant having the structure: HO—R—OH wherein R is a hydrocarbon diradical selected from the group consisting of polyesters, polyolefins, polyurethanes, poly(meth)acrylates and polyepoxide, any of which optionally includes heteroatom and/or silicone-containing linkages, and polysiloxanes, with a second reactant comprising a silyl having one end terminating with an isocyanate group and another end terminating with at least two alkoxy groups attached to a silicon atom thereof, wherein at least one of said alkoxy groups is not methoxy; and providing for reaction as a third reactant a methoxy silane in amounts and for a time sufficient to achieve alkoxy exchange with said alkoxysilyl endcapped polymer wherein said alkoxysilyl endcapped polymer includes methoxy groups.
