Polyamide-containing compositions and articles made therefrom

摘要

A solution from which filaments and films can be made by extrusion through a shaping orifice into a coagulant comprises a linear filament-forming polyamide of terephthalic acid dissolved in fortified phosphoric acid of more than 86% by weight concentration. Example 1 describes the interfacial polymerization of hexamethylene diamine with terephthaloyl chloride.
