发明名称 Verfahren zur Herstellung von Polyamiden
摘要 A method for improving the polymerization of polyamide compositions and the improved compositions formed thereby by polymerizing the polyamide in the presence of a small molar percent of a phosphonic acid salt of an organic diamine. The phosphonic acid salt increases the polymerization rate and results in a polymer of improved whiteness.
