摘要 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. Model polyamide aromatic polyamide triblock copolymers with different chain length of polycaprolactam and poly( p phenylene terephthalamide) were synthesized by one step high temperature polycondensation reaction The chemical structure and the properties of the copolymers were characterized by WAXD, FTIR and NMR
