Abstract
Process for preparing polyamide by anionically polymerizing lactam in the presence of an alkaline metal catalyst, an activator and at least one low molecular weight ester compound. The polymerization process is rapid and yields polyamides having good impact strengths. The process significantly reduces moulding time in reaction injection moulding.
