Abstract

In Example (8) copper-di-hexamethylenediamine iodide is made by reacting in aqueous solution, hexamethylene diamine, potassium iodide and copper sulphate. Examples (9), (10) and (11) describe analogous processes for the preparation of:-(9) copper di-hexamethylene diamine bromide; (10) copper di-propylene diamine iodide and (11) copper di-propylene-diamine bromide.ALSO:A method of improving the temperature stability of a polyamide comprises incorporating therein a minor amount of a metal complex of the general formula [Me-(X)n]Ym, where Me is a complex-forming metal from a sub-group or from Group VIII of the Periodic Table, X is ammonia, hydroxylamine, hydrazine, urea, biurel or an aliphatic, aromatic or heterocyclic amine, polyamine or polyimine either alone or together with one or more carbonyl compounds, water molecules or acid anions as additional ligands, n is an integer greater than 1, Y is an inorganic or organic acid radical or hydroxyl radical and m is a number expressing the relationship between the valency of the complex cation [Me(X)n] and the anion Y. Specified metals are copper, zinc, cadmium, chromium, iron, manganese, cobalt and nickel. Specified bases which may be present in the complexes are aniline, pyridine, quinoline, a , a 1-dipyridyl and phenylhydrazine, ethylene diamine, propylene diamine, hexamethylene diamine and o-phenylene diamine. Specified acid radicals are iodide, bromide, phosphite, phosphate, acetate and adipate. In the examples:-(1) e -caprolactam is polymerized in the presence of water, benzoic acid, potassium bromide and copper di-(ethylene diamine) hydroxide; (2) e -caprolactam is polymerized in the presence of water, benzoic acid and copper di-(hexamethylene-diamine) iodide; (3) hexamethylene diammonium adipate is polymerized in the presence of water, acetic acid, potassium iodide and copper di-(ethylene diamine) hydroxide; (4) e -caprolactam is polymerized in the presence of water, benzoic acid and copper-o-phenylene diamine sulphate; (5) e -caprolactam is polymerized in the presence of water, benzoic acid and nickel di-(hexamethylene diamine) iodide; (6) e -caprolactam is polymerized in the presence of water, butyl-ammonium acetate and cobalt tri-(hexamethylene diamine) iodide; and (7) e -caprolactam is polymerized in the presence of water, butyl ammonium acetate and copper di-hexamethyl-enediamine bromide.
