The subject-matter of the present invention is a process for making plasticization of an aliphatic polyamide with an external plasticizer of formula (II):
R1- [F1-A]m-F'1-R2 (II)
wherein:
- R1 and R2; identical or different, each represent a terminal group;
- m is an integer from 1;
- F1 and F'1, identical or different, each represent a divalent functional group having two chain links, the F groups being identical or different when m is 2 or more ;
A represents a divalent aliphatic, aromatic, aliphatic-aromatic or aromatic-aliphatic arm, the A arms being identical or different when m is 2 or more.
本发明的主题是用式(II)的外增塑剂对脂肪族聚酰胺进行增塑的工艺:
R1- [F1-A]m-F'1-R2 (II)
其中
- R1 和 R2;相同或不同,各自代表一个末端基团;
- m 是 1 以内的整数
- F1 和 F'1 相同或不同,各自代表具有两个链节的二价官能团,当 m 为 2 或 2 以上时,F 基团相同或不同;
A 代表二价脂肪族、芳香族、脂肪-芳香族或芳香-脂肪臂,当 m 为 2 或 2 以上时,A 臂相同或不同。
