ABSTRACT:
A molecular weight controller having particular application in the polymerization of a lactam, i.e., epsiloncaprolactam, to a polyamide, i.e., poly(epsiloncaprolactam). The molecular weight controller comprises a primary monofunctional amine, i.e., benzylamine, a primary monofunctional acid, i.e., acetic acid, and a salified aminoacid containing an aromatic, a cyclohexane, or cyclopentane moiety, i.e., 4-(aminomethylbenzoic acid salified with p-toluenesulfonic acid. The resulting polyamide has a reduced water extractable content.
