Abstract
The invention relates to high molecular weight (co)polyamides and to a process for the accelerated production of polyamides during melt polycondensation using a combination of aminocaprolactam (ACL) and/or lysine components and polycarboxylic acids and known catalysts and also, if desired, for the accelerated solid-phase post-condensation of the catalyst-containing (co)polyamides and to the polyamides produced by the processes.
