Camphorquinone
properties of styrene copolymers formed from BZ-containing monomers, a CQ-bearing monomer (±)-10-methacryloyloxycamphorquinone (MCQ) (another monomer with a 1,2-dicarbonyl moiety) was prepared and copolymerized with styrene to give MCQ/S copolymer bearing CQ pendant groups. Enantiopure MCQ is known from the
