Cast polyamide obtained by reacting (a) at least one catalyst for anionic polymerization of lactams, (b) at least one activator for anionic polymerization, (c) at least one tertiary amine and/or dibutyltin dilaurate as a co-activator, and (d) at least one lactam at temperatures of at least 80-130[deg] C, preferably 110-130[deg] C, is claimed. An independent claim is also included for producing the cast polyamide comprising mixing at least one lactam melt with the catalyst (a) and optionally the co-activator (c), at least one lactam melt with the activator (b) and optionally the co-activator (c), and optionally a lactam melt with the co-activator (c) at temperatures of at least 80-130[deg] C, preferably 110-130?C, and polymerizing into a mold, where the coactivator must be present in at least one of the lactam melts. |
