    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.

In an Example, a shepherd's check stocking is knitted from three yarns: nylon 6; nylon 6 modified by basic groups; and nylon 6 modified by oxyalkylate. The yarns are dyed pale red, blue, and dark red respectively. In another Example, yarns of nylon 6 and nylon 6 modified by oxyethylate are tufted into a twillwoven jute base fabric. The dyes employed may be acid, basic or disperse dyes, multicolour and tone in tone effects being obtained.
