用酰氯-固态缩聚法合成了不含金属盐催化剂的聚对苯二甲酸乙二酯(PET),其中含有不同量的二甘醇链结构,含量从0～16mol%。本文还对聚合物的链结构、分子量分布和聚合动力学作了初步探讨。
Poly (ethylene terephthalate) (PET) containing no metal salt catalyst was synthesized by acid chloride - solid state polycondensation. The content of ethylene glycol was from 0 to 16 mol%. In this paper, the polymer chain structure, molecular weight distribution and polymerization kinetics were also discussed.
