    摘要: A polycarbonate resin composition includes about 100 parts by weight of a base resin including a polycarbonate resin (A) and a polycarbonate-polysiloxane copolymer (B); and about 0.1 to about 10 parts by weight of polyalkylaryl siloxane (C) having a refractive index of about 1.42 to about 1.59. The composition can exhibit high gloss and blackness and can have excellent impact resistance, heat resistance, light resistance, and mar resistance (resistance to fine scratches).

    摘要: One aspect of the invention relates to a methacrylate resin prepared by suspension polymerization using a polyalkylacrylate-acrylic acid as a suspension stabilizer. The suspension stabilizer is used in an amount of about 0.05 to about 0.25 parts by weight per 100 parts by weight of a monomer mixture. Another aspect of the invention relates to a method for preparing a methacrylate resin, which comprises: preparing a mixture by mixing an initiator and a chain-transfer agent with a monomer mixture comprising at least about 50% by weight of alkyl methacrylate; and adding the mixture to an aqueous solution of polyalkylacrylate-acrylic acid to conduct suspension polymerization.

    摘要: One aspect of the invention relates to an acrylate-vinyl aromatic-unsaturated nitrile graft copolymer. The acrylate-vinyl aromatic-unsaturated nitrile graft copolymer can include: a double layered rubbery polymer comprising an inner core layer of alkylacrylate-vinyl aromatic copolymer and an outer core layer of alkylacrylate polymer; and a vinyl aromatic-unsaturated nitrile copolymer shell layer grafted onto the double layered rubbery polymer. Another aspect of the invention relates to a weatherable thermoplastic resin composition including the foregoing acrylate-vinyl aromatic-unsaturated nitrile graft copolymer.
