Description

technical field

[0001] The present invention relates to a thermoplastic resin composition formed by adding specific modified vinyl copolymer to styrene resin and polyamide resin. Background technique

[0002] Styrene-based resins are widely used as general-purpose thermoplastic resins because of their high rigidity, good appearance, good dimensional stability, and low water absorption. However, the chemical resistance, abrasion resistance, and heat resistance of styrene-based resins are insufficient, and their use under severe conditions is limited. In addition, crystalline thermoplastic resin compositions, especially polyamide resins, are widely used as engineering plastics because of their excellent chemical resistance, abrasion resistance, and heat resistance, but they have high water absorption, rigidity, and dimensional stability Sexual inadequacy.

[0003] Therefore, researches have been made on resin compositions that have the respective advantages of styrene-based ...
