PURPOSE: To obtain a thermoplastic resin composition having good dimensional stability and processability in high-temperature atmosphere, by adding a polyamide to a specific thermoplastic resin. n CONSTITUTION: A thermoplastic resin (A) is obtained by the copolymerization or graft polymerization of an aromatic monomer with alkenyl group (e.g., styrene) and 5W45wt% unsaturated dicarboxylic anhydride (e.g., maleic anhydride), together with, as needed, 0W35wt% vinyl monomer copolymerizable with the foregoing monomer and unsaturated dicarboxylic anhydride (e.g., acrylonitrile), in the presence of a rubbery polymer of a glass transition temperature of 0°C or less (e.g., polybutadiene) at a temperature of 40W170°C. Then 1W99wt% component (A) is melted and mixed with 99W1wt% polyamide (B) (e.g., nylon) at 200W280°C. n COPYRIGHT: (C)1982,JPO&Japio |
