<p><P>PROBLEM TO BE SOLVED: To provide a thermoplastic polyester elastomer composition which is little in volatile ingredients from a molded article and inhibits the contamination of a content due to the volatile ingredients, even without containing a hindered phenol group-having anti-oxidant and a hindered amine group-having photostabilizer, and to provide a method for producing the same. <P>SOLUTION: This polyester resin composition comprising polybutylene naphthalate and an aliphatic polyester diol is characterized by compounding the aliphatic polyester diol in an amount of 30 to 60 pts.mass per 100 pts.mass of the total amount of the polybutylene naphthalate and the aliphatic polyester diol. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
