Title: Stabilization of polyamides against the degradation effects of heat and oxygen
IPC: C08K3/16
Filed: 1952-02-27
Abstract: A polyamide is stabilized against the degradation effects of heat and oxygen by the addition of 0.001-0.03 per cent by weight of copper and 0.1-5 per cent by weight of chloride, bromide or iodide of sodium, potassium, magnesium or ammonium.  The copper is dissolved in the polyamide, e.g. by milling metallic copper into a polyamide whereby a soluble copper compound is formed, or by forming complexes between inorganic or organic copper compounds, e.g. oxides, acetate, butyrate, laurate, palmitate, or stearate, and diamines and/or polyamides.  If desired, 0.1-1 per cent of a phosphorus acid or alkali metal salt thereof may also be added.  A phenolic oxidation inhibitor such as catechol may also be used as a stabilizing ingredient.  The stabilizer compositions are preferably added to the polyam de-forming salt which is then condensed at 200-285 DEG  C. under pressure with gradual release of steam produced during the condensation.  It may, however, be added during condensation or blended with the formed molten polymer or blended, e.g. by tumbling with polyamide particles followed by extrusion of the mixture.  The phosphorus compounds when added to the polyamide-forming mixture catalyze the reaction and form polyamides of higher viscosity, unless the duration of the condensation is reduced.  A viscosity stabilizer such as acetic acid may be added to the reaction mixture.  Polyamides suitable for stabilization according to the invention may be produced according to the methods of Specifications 461,236, 461,237, 487,734, 557,544 or 619,707.  Plasticizers, resins, waxes, fillers and pigments may be incorporated with the stabilized polyamides which may be used for example for yarns, tyre cords, bristles, fabrics, mouldings, films, coatings, or electrical insulation. Example 1 describes a variety of specific compositions for inclusion in polyamide-forming reaction mixtures and indicates by tests the improvement in stability which is effected.  Example 2 describes the addition of a mixture of 0.015 per cent copper acetate, 1 per cent potassium bromide, 0.25 per cent mono-sodium phosphate and 1 per cent catechol to polycaprolactam for coating wire by extrusion. Specifications 487,737, [Group XL], 652,947 and 689,629 also are referred to.
