1.两种主要的商业聚酰胺是聚己二酰己二胺（尼龙66）和聚己内酰胺（尼龙6）。它们分别通过二元酸与二胺的直接酰胺化和ε-己内酰胺的开环聚合来制备。聚己二酰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容易通过预先形成1：1的铵盐：
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:
