Abstract: Laurolactam is polymerized by heat in the presence of (a) an oxyacid of phosphorus or a derivative thereof and (b) a mono- or dicarboxylic acid. Oxyacids and their derivatives specified ar phosphorous, phosphoric and hypophosphorous acids and their alkali metal and alkaline earth metal salts, anhydrides, C1- 5 alkyl esters, e.g. tri-methyl, ehthyl, propyl, butyl and pentyl, and halides, e.g. PCl3, PCl3 and PCl5 and polyacids derived therefrom. 0.001-3 mole per cent may be used. Carboxylic acids specified are: caproic, caprylic, capric, lauric, stearic, adipic, sebacic and mixtures thereof. 0.01-5 mole per cent may be used. The reaction may b continuous or batchwise at above 270 DEG C. and 1-25 atmospheres pressure. 5-50 mole per cent of water may be present and an inert atmosphere, e.g. N2, may be used. The product may be made into gears, bushes, screws, sheeting, coating powders, bristles, threads and filaments.
