【摘要】 用添加含磷共聚单体法合成了三种新四的含磷共聚酯。对萃洗后的反应产物进行了红外测试，对合成的反应条件进行了初步研究，并对所得产物的性能进行了对比。结果表明，含磷共聚单体的引入使共聚酯的玻璃化转变温度和熔点较聚酯降低，而冷结晶温度和结晶速度的变化则随引入的改性组分的不同而异。共聚酯的阻燃性、抗静电性均得到改善，染色性能也有所改善，表明该类共聚酯有可能用于制备多功能涤纶。更多还原

【Abstract】 n this paper,three kinds of copolyesters containing phosphorus have been synthesized and identified with IR.Their properties have also been investigated.The results showed that with the increase of the third compo-nent,the T_g and T_m of the polymer decreased,the T_c and crystallization rate changes mainly depand on thestructure of the third component.The properties of antistatic,flame resistance,dyeability of the copolyesterswere obviously improved.更多还原
