Abstract: In a process for the production of shaped articles from polyamides, a lactam with at least seven ring members is reacted with an alkali or alkaline earth metal or with an alkaline-reacting compound of an alkali or alkaline earth metal, and, after removal of water from the reaction medium and addition of an acid halide, anhydride, ester, or nitrile, the polymerization is initiated at a temperature which is above the melting point of the monomeric lactam and is carried out in a mould or on a support at a temperature which is at most about 40 DEG C. above the softening point of the polyamide. Specified lactams are E-caprolactam, oenanthic lactam, caprylic lactam and lauric lactam and their C-substitution products. The polymerization may be effected in the presence of fillers e.g. iron, aluminium or copper powder, finely divided molybdenum oxide, titanium dioxide, silica gel, dyestuffs, carbon black and glass fibres or fabrics. The examples describe the preparation of polyamides from E-caprolactam and/or caprylic lactam in the presence of potassium hydroxide, potassium methylate or sodium and benzoyl chloride, palmitic acid chloride, terephthaloyl chloride or triphenyl phosphate, methylene-bis-caprolactam being specified as a cross-linking agent in one example. Fillers specified in the examples are aluminium powder, copper powder, iron powder, glass fibres, glass fabrics and graphite.
