Patent ID: 6924339

Claim:
A thermally curable polymer composition comprising a hydroxyl-containing polymer, an amino cross-linking agent and a thermal acid generator, wherein the hydroxyl-containing polymer is a polymer comprising units m, n and o of the following formula: wherein R 1 is selected from the group consisting of H or methyl; R 2 is a univalent group such that the monomeric unit with the subscript m is selected from the group consisting of a substituted or unsubstituted C 6 -C 14 aryl acrylate unit and C 6 -C 14 aryl methacrylate unit wherein the substituted groups may be phenyl, C 1-4 alkyl or C 1-4 alkoxy; R 3 is a univalent group such that the monomeric unit with the subscript n is selected from the group consisting of hydroxyl functionalized C 1 -C 8 alkyl acrylate, methacrylate and C 6 -C 14 aryl unit, R 4 is a C 1 -C 10 linear or branched alkylene; p is an integer of from 1 to 5 with the proviso that there are no more than thirty carbon atoms in the [-R 4 O-] p ; R 5 is selected from the group consisting of C 1 -C 10 linear, branched or cyclic alkyl, substituted or unsubstituted C 6 -C 14 aryl, and substituted or unsubstituted C 7 -C 15 alicyclic hydrocarbon; and m is about 40 to 70, n is about 15 to 35, and o is about 15 to 25.
