Abstract: A copolymer latex for chipping-resistant aqueous paint capable of remarkably improving balance of chipping-resistance, strength of adherence with metal, water-resistance and high resistance for cycles of cool and heat is provided. This is achieved by a method for producing a copolymer latex using for chipping-resistant aqueous paint, the method comprising emulsion-polymerizing 20 to 80 parts by weight of a conjugated diene as a monomer, 0.5 to 15 parts by weight of an ethylenically unsaturated carboxylic acid as a monomer, 5 to 40 parts by weight of an aromatic vinyl compound as a monomer, 5 to 40 parts by weight of an unsaturated alkyl carboxylate as a monomer and optionally not more than 69.
Abstract: A flame-retardant and electromagnetic wave-shielding thermoplastic resin composition is provided, which comprises 100 parts by weight of a thermoplastic resin (A); from 0.5 to 30 parts by weight of a flame retardant of a halogen-free phosphate (B) represented by the following general formula (1): wherein R1, R2, R3, and R4 each independently represent a hydrogen atom or a monovalent organic group, at least one of R1, R2, R3, and R4 is a monovalent organic group, X is a bivalent organic group, k, l, m, and n are each independently 0 or 1, and N is an integer of 0 to 10; from 5 to 35 parts by weight of a metal-coated fiber (C); and from 3 to 30 parts by weight of a filler in a scaly shape or an acicular shape (D). Such a composition has excellent flame retardance, good appearance, and excellent molding flowability.
Abstract: An automobile exterior component, having good balance between impact resistance and fluidity and being excellent in coating heat resistance and rigidity, which is prepared by performing urethane coating or melamine coating on a molded article obtained by molding a resin composition which comprises a polyamide resin (A); a grafted polymer (B) prepared by graft polymerizing an aromatic vinyl monomer and a vinyl cyanide monomer in the presence of a diene rubber;
an unsaturated carboxylic acid-modified copolymer (C) which has a reduced viscosity of 0.2 to 0.5 dl/g and is prepared by polymerizing an unsaturated carboxylic acid monomer, an aromatic vinyl monomer and a vinyl cyanide monomer;
a copolymer (D) prepared by polymerizing an aromatic vinyl monomer and a vinyl cyanide monomer; and
talc, wherein the amount ratio of (A), (B), (C) and (D) is in a specific range.
