NOVELTY - A modified polycarbonate comprises components and/or reaction product of polycarbonate matrix, acid (ester) monomer and initiator. USE - The modified polycarbonate is used in composite material in optical, communication, electronic, automobile, medical treatment and aerospace field (all claimed). ADVANTAGE - The introduction of acid (ester) monomers into polycarbonate matrix can promote interaction between modified polycarbonate materials and other polymer materials during compounding, and improves wettability and two-phase interface of inorganic materials in polycarbonate compatibility, interfacial bonding strength and mechanical properties of multi-component composite system and compatibility. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a method for preparing modified polycarbonate comprising melting and mixing raw material comprising polycarbonate matrix, acid (ester) monomer and initiator; and (2) a composite material comprising polyethylene, polypropylene, polyformaldehyde, polymethyl methacrylate, polystyrene, methyl methacrylate/butadiene/styrene copolymer, acrylonitrile/butadiene/styrene copolymer, acrylonitrile/acrylic ester/styrene copolymer, acrylonitrile/styrene copolymer, styrene/maleic anhydride random copolymer, acrylonitrile/styrene/maleic anhydride random copolymer, polyethylene glycol terephthalate, polybutylene terephthalate, polybutylene succinate, polybutylene adipate, poly (butylene succinate/terephthalate), polybutylene adipate/terephthalate, glass fiber, carbon fiber, aramid fiber, graphene, carbon nanotube or modified polycarbonate.
