Composition comprises at least one lactam compound and at least one activator for the anionic polymerization of the lactam compound, where the activator comprises an isocyanate compound (I). Composition comprises at least one lactam compound and at least one activator for the anionic polymerization of the lactam compound, where the activator comprises an isocyanate compound of formula (I). R 1>lactam, preferably caprolactam. An independent claim is included for the preparation of cast polyamides comprising polymerizing the lactam compound, activator and optionally further at least one catalyst (as a melt) at 80-160[deg] C, where the catalyst is lactam-magnesium halide, alkali-alumo dilactamate or alkali and/or alkaline earth lactamate.
