    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.

    Abstract: Anionic polymerization of lactams is promoted by a compound of formula R-C­C-X-R1 where R = H or a substituted or unsubstituted hydrocarbon radical, R1 = a substituted or unsubstituted hydrocarbon radical and X = O or S. Lactams specified are butyro-, capro-, oenantho-, capryl-, decyl-, undecyl- and lauryl-lactams and mixtures thereof. Promoters specified are octyloxybutyne, ethoxyheptyne, pentoxyethyne, phenoxyethyne, naphthoxyethyne, isopropoxyethyne, butoxybutyne, methoxybutyne, methoxypropyne, methoxyethyne, methioethyne, pentylthiobutyne, ethylthiopropyne, propylthiopentyne and methoxyhexyne. Catalysts specified are sodium caprolactam, Al(Pri)3, ZnEt2, alkali-metal alkyls, alkali-metals and alkaline earth metals and their hydrides, oxides, hydroxides, and carbonates, and alkyl and aryl magnesium bromides. The lactam may be melted, mixed with 0.1-10 mole per cent of catalyst and heated to the polymerization temperature before adding 0.05-10 mole per cent of promoter. The polymerization temperature may be between the melting points of the monomer and polymer or between 90 DEG and 250 DEG C. The initial temperature may rise due to the exothermic reaction. Other additives may be dyes, fillers, e.g. wood flour, carborundum, carbon black, shale, coal dust, coke dust, natural or synthetic fibres, polystyrene, polyformaldehyde, polypropylene, polyethylene, other polyamides, phenoplasts, melamine/formaldehyde and urea/formaldehyde resins.
