摘要： Homopolymers and copolymers are prepared which contain side chains of Werner complexes of carboxylic acid groups coordinated with chromium. Particularly useful are such polymers with side chains provided by the homopolymerization and copolymerization of methacrylato chromic chloride complexes. These materials have many uses including as coupling agents for bonding resins to other materials.
