The invention encompasses the process for the preparation of a cross-linked aramid polymer comprising the step of heating a non-crosslinked polymer comprising the repeating unit of formula (I) at a temperature comprised of from 150 to 400° C. for a period of time comprised of from 1 second to 20 minutes, wherein A and B are independently selected from meta-phenylene and para-phenylene, and R1 and R2 are independently selected from H and N
3
, with the proviso that at least one of R1 and R2 is N
3
and R1 and R2 are attached to any of the positions 1, 2, 3, or 4 in para-phenylene and 1, 2, 3 in meta-phenylene; and the obtained cross-linked aramid polymer.
本发明涵盖了制备交联芳纶聚合物的过程,包括以下步骤:将式(I)重复单元组成的非交联聚合物在温度为150°C至400°C之间加热1秒至20分钟的时间,其中A和B独立地选择自间苯和对苯基苯,R1和R2独立地选择自H和N3,但至少其中之一为N3,且R1和R2附着于对苯基苯的1、2、3或4位和间苯的1、2、3位中的任意一位;以及所得到的交联芳纶聚合物。
