linked 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.
