摘要

1. 两种主要的商业聚酰胺是聚己二胺(尼龙66)和聚己内酰胺(尼龙6)。它们分别由二酸与二胺直接酰胺化和-己内酰胺开环聚合生产。聚己二胺是由己二胺和己二酸合成的[1]。胺羧基的化学计量平衡很容易通过1:1的铵盐的初步形成得到:

Progress in the Area of Degradation and Stabilization of Nylon 66

1. INTRODUCTION The two principal commercial polyamides are poly(hexamethylene adipamide) (nylon 66) and polycaprolactam (nylon 6). They are produced by direct amidation of a diacid with a diamine and ring-opening polymerization of ɛ-caprolactam, respectively. Poly(hexamethylene adipamide) is synthesized by hexamethylene diamine and adipic acid [1]. A stoichiometric balance of amine carboxylic group is readily obtained by the preliminary formation of a 1:1 ammonium salt:
