Abstract
Methods of forming polycarbonate graft copolymers are provided. In particular, a polycarbonate polymer or copolymer containing allyl groups provides the backbone for the graft copolymer, and pendant chains are attached to the copolymer through the allyl groups. The graft copolymers exhibit a combination of high transparency, good graft levels, good scratch resistance, and/or good anti-fog properties.
