PURPOSE:To improve the abrasion resistance of a product by compounding 0.01-50wt. part polyamide family resin having ester family bonding with 100wt. part styrene family resin or polyphenylene ether family resin. CONSTITUTION:A resin composition is injection molded, and in said composition, 0.01-50wt. part polyamide copolymer having the ester bonding composed of polyamide and polyester block or polyamide block and polyol block is compounded with 100wt. part styrene family resin or polyphenylene ether family resin. The both terminals of the polyester amide made of polyamide block and polyester block are diol or acid preferably. This styrene family resin or polyphenylene family resin is excellent in frictional and abrasive property by injection molding it only.
