Abstract
A grafted aromatic polycarbonate resin is produced by melt-kneading a graft precursor comprising a mixture of 35 to 95% by weight of aromatic polycarbonate resin particles and 65 to 5% by weight of vinylic copolymer containing active oxygen, the vinylic copolymer being present in the aromatic polycarbonate resin particles, thereby subjecting to grafting reaction of the aromatic polycarbonate resin and the vinylic copolymer, where the grafting reaction can be sufficiently carried out and thus the grafted polycarbonate resin is useful for molding materials for optical disks, optical lenses, etc. a polymer blend-compatible agent, adhesives, paints, etc.
