With the use of macromonomers that have a dicarboxyl group, polycarbonate–poly(methyl methacrylate) (PC–PMMA) graft copolymers were prepared, and the relationship between the length of PMMA branches and Vickers hardness of the graft copolymer was investigated. With the use of the PC–PMMA graft copolymer as a modifier to improve the surface hardness of PC, Vickers hardness of PC/PC–PMMA blend polymers was examined. PC/PC–PMMA blend polymers are more transparent than PC/PMMA blend polymers. PC/PC–PMMA blend polymers are superior in Vickers hardness to PC/PMMA blend polymers, although the content of PMMA in PC/PC–PMMA blend polymers is smaller than that of PC/PMMA blend polymers. © 2002 Wiley Periodicals, Inc.
