<p>PROBLEM TO BE SOLVED: To provide a polyester resin composition generating no problems of drawdown or crystallization during direct blow molding, excellent in heat stability and capable of providing a direct blow molded article excellent in transparency with good productivity.SOLUTION: A polyester resin composition contains 0.1 to 1.0 mass% of tetrakis[methylene-3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate]methane in a polyester resin having acid component of which 50 to 95 mol% is terephthalic acid, 2 to 20% is furan dicarboxylic acid, and a glycol component of which 80 mol% or more is ethylene glycol, and 5×10-5 mol to 4.0×10-4 mol of a germanium compound based on 1 mol of the acid component of the polyester resin, and has intrinsic viscosity (IV) of 0.8 to 1.5 and swell ratio (SW) of 1.2 to 1.4.</p> |
