    • The present invention relates to the combination of halogen-free flame retardant additives in a copolyester to improve the flame retardant properties of the copolyester composition while retaining clarity and impact properties, methods of making the copolyester composition and articles made from the copolyester composition. More specifically, the present invention relates to the use of a polymeric sulfonyl and phosphonate containing flame retardant compound in copolyester compositions to improve the flame retardant properties while retaining clarity, glass transition temperature, impact properties, methods of making said copolyester compositions and articles therefrom.
    • 本发明涉及在共聚酯中组合无卤阻燃添加剂以改进共聚酯组合物的阻燃性能同时保持透明度和冲击性能,制备共聚酯组合物和由共聚酯组合物制成的制品的方法。 更具体地说,本发明涉及含有聚合物磺酰基和膦酸酯的阻燃剂化合物在共聚酯组合物中用于改进阻燃性能同时保持透明度,玻璃化转变温度,冲击性能,由此制备所述共聚酯组合物和制品的方法。
