Patent ID: 8030425

Claim:
A vinyl addition polymer comprising a backbone having at least three distinct types of repeat units derived from norbornene-type monomers, such monomers being independently selected from monomers represented by Formula I: where X is selected from —CH 2 —, —CH 2 —CH 2 — and —O—; m is an integer from 0 to 5; and each occurrence of R 1 , R 2 , R 3 , and R 4 is independently selected from one of the following groups: H, C 1 to C 25 linear, branched, and cyclic alkyl, aryl, aralkyl, alkenyl, and alkynyl; or C 1 to C 25 linear, branched, and cyclic alkyl, aryl, aralkyl, alkenyl, and alkynyl containing one or more hetero atoms selected from O, N, and Si; or a glycidyl ether containing group represented by Formula II: wherein A is a linking group selected from C 1 to C 6 linear, branched, and cyclic alkylene and R 23 and R 24 are each independently selected from H, methyl, and ethyl; or any combination of two of R 1 , R 2 , R 3 , and R 4 linked together by a linking group selected from C 1 to C 25 linear, branched, and cyclic alkylene and alkylene aryl; and with the proviso that a first monomer of the at least three distinct types of monomers represented by Formula I comprises at least one glycidyl ether pendant group, a second monomer of the at least three distinct types of monomers comprises at least one aralkyl pendant group and a third monomer of the at least three distinct types of monomers comprises at least one alkyl pendant group.
