Abstract: A lactam is polymerized anionically in the presence of a catalyst and as promoter 1,3-diphenyl - 1 - benzoyloxy - 3 - oxo - 2 - azapropylene-1. Lactams specified are butyrolactam, caprolactam, oenantholactam, capryllactam, decyllactam, undecyllactam, laurinolactam and mixtures thereof. Catalysts specified are: sodium caprolactam, Al(oPri)3, ZnEt2, alkali metal alkyls, alkali metals, alkaline earth metals and their hydrides, oxides, hydroxides, carbonates and alkyl and aryl magnesium bromides; 0.1-10 mole per cent catalyst and 0.05-2% promoter may be used. The three reactants may be mixed simultaneously or the catalyst may be added to the molten lactam and this heated to the polymerization temperature before the promoter is added. The polymerization temperature may be between the m.p. of the lactam and that of the polymer or between 90 DEG and 250 DEG C. The initial polymerization temperature of 90-150 DEG C. may rise due to the exothermic reaction. Additives which may be present are blowing agents, e.g. a hydrocarbon, dyes, fillers, e.g. wood flour, carborundum, carbon black, powdered shale, coal dust and coke dust, threads and fabrics of natural or synthetic fibres, polystyrene, polyformaldehyde, polypropylene, polyethylene, a polyamide, a phenoplast or a urea or melamine/aldehyde resin.
