Polyester resin composition

摘要

A polyester resin composition comprises 5-50 wt.% of a polyamide and 0.01-2 pts.wt. of a tricarboxylic acid. A polyester resin composition (I) is prepared by melt-kneading (A) 100 pts.wt. of a mixture (II) comprising 5-50 wt.% of a polyamide resin produced by polymerization of a diamine component containing at least 70 mole % of m-xylylenediamine, a dicarboxylic acid component containing at least 70 mole % of adipic acid and 50-95 wt.% of a polyester resin prepared by polymerization of a dicarboxylic acid containing at least 70 mole % of an aromatic dicarboxylic acid and a diol component containing at least 70 mole % of an aliphatic diol and (B) 0.01-2 pts.wt of a tricarboxylic acid. An independent claim is included for a molded article, preferably a film, sheet or thin-wall hollow container prepared from (I).
