Title:
THERMOPLASTIC RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP3158525
Kind Code:
B2
Abstract:
PURPOSE: To obtain a thermoplastic resin composition having excellent impact resistance, chemical resistance, heat-resistance and rigidity by compounding a specific graft copolymer, a polyolefin, a modified vinyl polymer and a polyamide at specific ratios.
CONSTITUTION: The objective composition is produced by compounding (A) 5-85wt.% of a graft copolymer produced by the graft-polymerization of (i) 5-80 pts.wt. of a rubber polymer such as polybutadiene with (ii) 95-20 pts.wt. of a monomer mixture composed of 20-90wt.% of an aromatic vinyl monomer such as styrene, 80-10wt.% of a vinyl cyanide monomer and/or an unsaturated carboxylic acid alkyl ester monomer and 0-40wt.% of other vinyl monomer copolymerizable with the above monomers with (B) 95-15wt.% of a polyolefin and compounding 100 pts.wt. of the obtained composition with (C) 3-70 pts.wt. of a modified vinyl polymer produced by copolymerizing an aromatic vinyl compound, vinyl cyanide and an α,β-unsaturated carboxylic acid and (D) 1-50 pts.wt. of a polyamide resin.
