Abstract
A copolymer composition including a copolymer having repeat units of structural formula I: where X is selected from —CH—, —CH—CH— and O; m is an integer from 0 to 5; and each occurrence of R-Rare independently selected from H; Cto Clinear, branched, and cyclic alkyl, aryl, aralkyl, alkaryl, alkenyl and alkynyl that can include one or more hetero atoms selected from O, N, and Si; a group that contains an epoxy functionality; —(CH)C(O)OR; —(CH)C(O)OR; —(CH)OR; —(CH)OC(O)R; —(CH)C(O)R; —(CH)OC(O)OR; and any combination of two of R, R, R, and Rlinked together by a linking group. A portion of the repeat units having structural formula I contain at least one epoxy functional pendant group. The copolymer composition can be included with a material that photonically forms a catalyst in a photodefinable dielectric composition, which can be used to form a photodefinable layer on a substrate.
