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. |
