Beschreibung
Zusammenfassung:	A polyester composition comprising 99.9 to 80 wt % of a thermoplastic polyester containing an antimony compound and 0.1 to 20 wt % of a partially aromatic polyamide, wherein a 4 mm-thick molded plate formed by molding the thermoplastic polyester at 290° C. has a haze value of 10% or lower, and wherein the phosphorus atom content in the partially aromatic polyamide (P1), the partially aromatic polyamide content in the polyester composition (A), and the antimony atom content in the thermoplastic polyester (S) satisfy a specific formula, wherein a 4 mm-thick molded plate produced by molding the polyester composition at 290° C. has a haze value of 20% or lower. The polyester composition can be molded into a hollow molded article (e.g., a bottle) at a high productivity rate, which is not deteriorated in transparency or color, and which is excellent in flavor-conserving property, thermal stability and gas-barrier property.
