Abstract
Provided are a resin composition which is colored little and has excellent gas barrier properties, transparency and mechanical properties, a method for producing it, and a shaped article. The composition is a polyester resin composition comprising from 2 to 30% by weight of a specific polyamide resin (A), from 69.5 to 97.99% by weight of a specific polyester resin (B) and from 0.01 to 0.5% by weight of a di- and/or tri-polycarboxylic acid compound (c), which satisfies a≦b, 60 ≦a+b≦150, 1≦c×Cc≦20, 1≦c×Cc/(a×Ca)≦12 (wherein a is a concentration of the terminal amino group of the polyamide resin (A), b is a concentration of the terminal carboxyl group of the polyamide resin (A), c is a concentration of the carboxyl group in the polycarboxylic acid compound (C), Cc is a concentration of the polycarboxylic acid compound (C) in the polyester resin composition, and Ca is a concentration of the polyamide resin (A) in the polyester resin composition (g/g). The method is for producing the resin composition; and the shaped article is obtained by shaping the resin composition.
