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.

Abstract: A crystalline polypropylene of mean intrinsic viscosity 1.3-2.3 and of which at least 94% has a range of viscosity of 0.5-3.0 is used to prepare stretched fibres, threads and woven and non-woven fabrics. The polypropylene may be prepared by mechanically degrading, e.g. in a high shear gradient of a screw extruder, a polypropylene of mean intrinsic viscosity of at least 6 which may first be degraded by oxidation.
