Abstract: 1,159,599. Stabilizing polyamides. BADISCHE ANILIN- & SODA-FABRIK A.G. 28 Oct., 1966 [29 Oct., 1965], No. 48418/66. Heading C3R. Polyamides are stabilized against heat and light by incorporating 0À05 to 2À5 wt. per cent of an inorganic iodide and 0À01 to 0À5 wt. per cent of a copper complex containing the grouping wherein each R is independently H or an unsubstituted or hydroxy-, alkoxy- or halosubstituted and X is a radical having 2 to 12 atoms in the chain linking the two N atoms. Various compounds are mentioned. In the examples potassium iodide and the copper salt of tetramethylene-bis (iminophenylacetic acid) is incorporated during the polymerization of nylon 6 or 66/6 of K-values from 62 to 86.
