聚对苯二甲酸乙二酯的结晶性能研究——Ⅰ.“杂质”对结晶性能的影响

Study oF Crystallinity of Poly(ethylene terephthalate)——Ⅰ.Effect of“Impurity”on the Crystallinity of Terylene

研究了“杂质”对聚对苯二甲酸乙二酯的结晶性能的影响,共缩聚第三组分在晶区与非晶区的分配,表明共缩聚第三组分不进入晶区.

We have studied the effect of “impurity” on crystallinity of poly(ethylene te-rephthalate),and the distribution of the third comonomer in the crystalline andnon-crystalline regions of copolycondensates.It shows that the third comonomeris absent in the crystalline region.
