Abstract: Heat stabilized synthetic polyamide compositions are prepared by incorporating therein a mixture of a phenolic antioxidant and metal hypophosphite, a copper compound and metal halide. A typical embodiment includes polyamides which are stabilized with 1,2-bis(3,5-di-t-butyl-4-hydroxyphenyl)-propionamido)ethane and sodium hypophosphite, copper acetate and potassium iodide.
Abstract translation: 通过在其中掺入酚类抗氧化剂和次磷酸金属，铜化合物和金属卤化物的混合物来制备热稳定的合成聚酰胺组合物。 典型的实施方案包括用1,2-双[3,5-二叔丁基-4-羟基苯基] - 丙酰胺基]乙烷和次磷酸钠，乙酸铜和碘化钾稳定的聚酰胺。

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.
