Abstract
The present invention provides a resin composition which is lowly water-absorbent and is excellent in properties such as mechanical strength, flexibility and heat resistance while improving the compatibility of the conventional resin composition comprising a polyamide resin and a thermoplastic polyester resin, and which comprises 100 parts by weight of a mixture composed of: PA1 (A) 10 to 90% by weight of a polyamide resin having a molar ratio of the terminal carboxyl group to the terminal amino group of 1.5 or more, and PA1 (B) 90 to 10% by weight of a thermoplastic polyester resin, and incorporated therein, and PA1 (C) 0.1 to 10 parts by weight of a vinylic copolymer comprising 40 to 99% by weight of a specified vinyl monomer and 60 to 1% by weight of a specified vinyl monomer having a glycidyl ester group.
