研究了各种合成聚己内酰胺- 聚芳酰胺- 聚己内酰胺三嵌段共聚物的方法. 采用高温溶液直接缩聚法, 合成了具有不同长度的聚己内酰胺链段和聚对苯二甲酰对苯二胺链段的三嵌段共聚物, 并对这些三嵌段共聚物进行了表征.
Various methods of synthesizing polycaprolactam-polyaramid-polycaprolactam triblock copolymers have been studied. The triblock copolymers of polycaprolactam segments and poly (p-phenylene terephthalamide) segments with different lengths were synthesized by direct polycondensation at high temperature. The triblock copolymers were characterized.
