The invention relates to accelerated polycondensation of suitable monomer melts in the presence of small amounts of lysine components and approximately equivalent amounts of a polycarboxylic acid, which may be subjected to a thermal post-condensation reaction and is to be subjected to a thermally deformable, slightly branched aliphatic (co) polyamide of high molecular weight, with increased melt viscosity and pronounced structural viscosity , and a process for polycondensation. The lysine components used are lysine, lysine hydrate, esters of lysine with low alcohols, or also lysine hydrochloride (the latter in the presence of approximately equivalent amounts of likewise added bases for binding the HCl). |
