<p>PROBLEM TO BE SOLVED: To obtain a polyester resin composition capable of providing a blow- molded vessel excellent in gas-barrier properties, heat resistance, pressure resistance and transparency when molding the blow-molded vessel, and further to provide the blow molded vessel by using the composition. SOLUTION: The polyester resin composition comprises (A) a polyethylene phthalate composed of a repeating unit derived from a dicarboxylic acid component comprising terephthalic acid and/or its ester-formable derivative, and a glycol component comprising ethylene glycol and/or its ester-formable derivative, and (B) a syndiotactic polypropylene in an amount of 0.01-1,000 ppm, and the blow-molded vessel is formed out of the composition.</p> |
