Abstract

Process for obtaining polyamide compositions, characterized in that it comprises intimately mixing an organophosphonic acid of the general formula: ** (see formula) ** Wherein r is an organic radical and a metal compound selected from metal salts of saturated or unsaturated carboxylic acids, metal oxides and hydroxides, with a polyamide under melting conditions.
