Abstract: IN THE MANUFACTURE OF POLYAMIDES FOR INDUSTRIAL USES IN GENERAL, SUCH AS FOR THE PRODUCTION OF FIBERS, YARNS MOULDED ARTICLES AND THE LIKE, THE IMPROVEMENT IS HEREIN DISCLOSED, WHICH CONSISTS IN THE CONCURRENT ADDITION OF A STABILIZING COPPER COMPOUND AND OF AN ALLYL HALIDE, IN WHICH THE HYDROGEN ATOM OF THE DOUBLE-BONDED METHYLENE GROUPING IS POSSIBLY SUBSTITUTED BY AN ALIPHATIC RADICAL. ALLYL CHLORDE HAS PROVEN TO BE THE MOST ADVANTAGEOUS IN ITS CLAS. VERY SUPRISINGLY, THE PRESENCE OF AN ALLYL CHLORIDE AS DEFINED ABOVE HAS EXHIBITED AN UNPREDICTABLE ACTIVITY IN NUETRALIZING THE DISCOLOURATION WHICH WOULD BE OTHERWISE EXPERIENCED SHOULD THE COPPER COMPOUND BE USED ALONE. PRODUCTS HAVING AN OUTSTANDINGLY HIGH WHITENESS RATING HAVE BEEN THUS OBTAINED.

Abstract: An antistatic additive for polyamide fibres is disclosed, which is a polyoxyethylene having an average molecular weight of 20,000 and a very narrow range of molecular weight, the molecular dispersion index ranging from 1.02 to 1.2. The antistatic mode of action of the additive according to the invention is not completely elucidated, but outstanding and persistent antistatic properties have been experimentally ascertained. The maximum amount to be used is 0.5% by weight with respect to the polymer; higher amounts are in no wise detrimental, but afford no advantage.

Abstract: A method is disclosed for the production of peroxide-like derivatives of ozonides by ozonization of the correspoding olefins, comprising the step of placing an olefin in the presence of ozone in solution in a solvent mixture which comprises at least a nonpolar solvent (inert with respect to the olefin concerned) and at least a polar solvent, in which the as formed ozonide is reactively dissolved, a heavy weight phase being formed which contains the peroxide-like derivative. The derivative in question is removed from the reaction environment so as to substract it from superoxidation and polymerization effects.
