聚酰胺PA 6-6的合成方法
摘要：
本发明涉及一种聚酰胺PA 6-6合成方法，其包括：-第一步，在水的存在下，使式(I)R0-OOC–(CH2)4–COO-R'0(I)的化合物与六亚甲基二胺(HMDA)在小于或等于60℃的温度下反应，以形成反应介质，其中R0和R'0可相同或不同，代表H或包含1至4个碳原子的直链或支链烷基，然后-第二步，将反应介质加热至大于或等于200℃的温度；其中反应介质还包含：-式(A)的化合物：R1-OOC-(CH2)n-CH＝CH-(CH2)n-COO-R2(A)-和/或式(B)的化合物：R3-(CH2)m-CH＝CH-(CH2)n-COO-R4(B)，其中：R1、R2和R4可相同或不同，代表H或包含1至4个碳原子的直链或支链烷基，R3代表-CN或-COOR5，R5代表H或包含1至4个碳原子的直链或支链烷基，m代表0、1或2并且n是7和13之间的整数，包括端值。
摘要（英）：

The present invention relates to a polyamide PA6-6 synthesis process, comprising a first step of reacting, in the presence water, a compound of formula (I)R0CCO-(CH2)4-COOR '0(I), in which R0 and R 'O, which may be identical or different, represent H or a linear or branched alkyl radical comprising from 1 to 4 carbon atoms, with hexamethylenediamine (HMDA) at a temperature less than or equal to 60DC, so as to form a reaction medium, then a second step of heating the reaction medium to a temperature greater than or equal to 200DC; wherein the reaction medium also comprises a compound of formula(A); R1-COO-(CH2)n-CH=CH-(CH2)n-COO-R2(A)-and/or a compound of formula (B); R3-(CH2)m-CH=CH-(CH2)n-COO-R4(B) in which: R1, R2 and R4, which may be identical or different, represent H or a linear or branched alkyl radical comprising from 1 to 4 carbon atoms, R3 represents -CN or -COOR5, R5 representing H or a linear or branched alkyl radical comprising from 1 to 4 carbon atoms, R3 represents -CN or -COOR5, R5 representing H or a linear or a branched alkyl radical comprising from 1 to 4 carbon atoms, m represents 0, 1 or 2 and n is an integer between 7 and 13, limits inclusive.
