Patent ID: 8003727

Claim:
A scratch resistant flame retardant thermoplastic resin composition consisting essentially of: 100 parts by weight of a base resin consisting essentially of (A) about 1 to about 99% by weight of a polycarbonate resin and (B) about 99 to about 1% by weight of a modified methacrylate resin, wherein said modified methacrylate resin is a copolymer consisting of about 50 to about 99.9% by weight methyl methacrylate (MMA), a difunctional monomer selected from the group consisting of glycidyl methacrylate, allyl glycidyl ether, methacrylic acid anhydride, 2-hydroxy ethyl acrylate, 2-hydroxypropyl acrylate, monoglycerol acrylate, and mixtures thereof, and optionally at least one additional monofunctional unsaturated monomer selected from the group consisting of methacrylates other than MMA, acrylates, unsaturated carboxylic acids, acid anhydrides and monofunctional vinyl group-containing monomers; (C) about 1 to about 50 parts by weight of a flame retardant; and optionally an additive selected from the group consisting of an impact modifier, flame retardant aids, anti-dropping agents, weather stabilizers, antioxidants, plasticizers, heat stabilizers, light stabilizers, compatibilizers, pigments, dyes, inorganic fillers, and mixtures thereof.
