Abstract: PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition having high and balanced transparency, chemical resistance and color stability. SOLUTION: The thermoplastic resin composition contains a rubber-containing graft copolymer dispersed in a vinyl copolymer. The ratio of the triple sequence of the acrylonitrile monomer unit existing in the acetone-soluble fraction of the thermoplastic resin composition is

Abstract: PROBLEM TO BE SOLVED: To obtain a rubber-containing styrenic thermoplastic resin composition that has well-balanced transparency, chemical resistance, color tone stability, and thermal stability on processing. SOLUTION: The objective resin composition is produced by formulating an anti-oxidizing agent to a rubber-reinforced styrenic resin that comprises a graft copolymer produced by polymerizing a vinyl monomer and an unsaturated carboxylic alkyl ester monomer in the presence of a rubber polymer and a vinyl copolymer obtained from vinyl monomer and an unsaturated carboxylic alkyl ester monomer in which the difference in refractive index between the rubber-reinforced styrenic resin and the anti-oxidizing agent is

Abstract: PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition which is excellent in sliding properties, especially on resin moldings and metals, is a transparent, rubber-reinforced thermoplastic styrene resin composition, and is excellent in mechanical strengths such as impact resistance and stiffness. SOLUTION: A thermoplastic resin composition which is excellent in sliding properties, especially on resin moldings and metals, is a transparent, rubber- reinforced thermoplastic styrene resin composition, and is excellent in mechanical strengths such as impact resistance and stiffness can be obtained by compounding (I) 100 pts.wt. rubber-reinforced styrene resin containing (a) an unsaturated carboxylic acid alkyl ester monomer with (II) 0.1-3.0 pts.wt. fatty acid amide.

Abstract: PROBLEM TO BE SOLVED: To obtain a transparent thermoplastic resin composition excellent in color tone of a molded product, transparency, impact resistance and moldability. SOLUTION: This transparent thermoplastic resin composition comprises 100 pts.wt. of a thermoplastic resin composition (I) comprising a graft copolymer (A) obtained by graft copolymerizing, to a rubbery polymer (a), at least one vinyl monomer selected among an aromatic vinyl monomer (b), a vinyl cyanide monomer (c), an alkyl unsaturated carboxylate monomer (d) and other vinyl monomers (e) copolymerizable therewith, or a mixture thereof and at least one or more vinyl copolymers (B) comprising at least one vinyl monomer selected among an aromatic vinyl monomer (b), a vinyl cyanide monomer (c), an alkyl unsaturated carboxylate monomer (d) and other vinyl monomers (e) copolymerizable therewith, and added thereto, 0.01-2 pts.wt. of a hypophosphite (II), and the difference between the respective refractive indexes of the rubbery polymer component (a) and the matrix resin component is 0.03 or less.
