Abstract

Disclosed is a moisture curable silane modified terpolymer comprising a polyether segment, a segment of polytetrahydrofuran or polycarbonate, a polysiloxane segment and terminal amino silane groups joined to the terpolymer via urethane linkages and wherein the polyether segment comprises at least 70% by weight based on the total weight of the silane modified terpolymer. Also disclosed is a method of forming moisture curable silane modified terpolymer.
