Abstract

Conductor wires are insulated by coating with an amide-modified polyamide made by (A) reacting by mixing at least one amide or polyamide having two terminal primary aromatic amino groups, with pyromellitic dianhydride in the presence of a solvent for the reactants or (B) reacting by mixing at least one primary aromatic diamine with pyromellitic dianhydride in the presence of a solvent for the reactants and reacting the product with at least one aromatic dibasic acid, halide, the resultant polymeric soluble intermediate being converted to an insoluble solid product by heating. In Example (XVII) a solution in acetamide of a reaction product of m-amino-benzoyl-p-amino-anilide and pyromellitic dianhydride is applied to a copper wire and cured by heat.ALSO:A process for making linear amide-modified polyimides comprises (A) reacting by mixing at least one amide or polyamide having two terminal primary aromatic amino groups, with pyromellitic dianhydride in the presence of a solvent for the reactants or (B) reacting by mixing at least one primary aromatic diamine with pyromellitic dianhydride in the presence of a solvent for the reactants and reacting the product thus obtained with at least one aromatic dibasic acid halide; whereby a soluble polymeric intermediate is formed, and heating said intermediate to convert the same to an insoluble solid product. The intermediates which contain amido acid groups are soluble in dimethyl formamide, acetamide and sulphoxide, Nmethyl-2-pyrrolidone and aqueous sodium hydroxide and bicarbonate and ammonium hydroxide. In the examples:- (I) a polyamide is made from m-phenylene diamine and isoand tere-phthaloyl chloride; (II) the polyamide of (I) is reacted with pyromellitic dianhydride; (III) and (IV) polyamides are made from mphenylene diamine and isophthaloyl chloride and reacted with pyromellitic dianhydride; (V), (VI), (XV) and (XVI) polyamides are made from m-phenylene diamine and iso- and terephthaloyl chloride and reacted with pyromellitic dianhydride; (VII) a polyamide is made from 4:41-methylene dianiline and iso- and terephthaloyl chloride and reacted with pyromellitic dianhydride; (VIII) m-phenylene diamine is reacted with pyromellitic dianhydride and the product with isophthaloyl chloride; (IX) 4:41methylene dianiline is reacted with pyromellitic dianhydride and the product with isophthaloyl chloride; (X) isophthaloyl-m-aminoanilide is reacted with pyromellitic dianhydride; (XI) N:N1-bis(aminobenzoyl)-m-phenylene diamine is reacted with pyromellitic dianhydride; (XII) p-aminobenzoyl-m-aminoanilide is reacted with pyromellitic dianhydride; (XIII) bis(m-aminobenzoyl)-p:p1-diaminodiphenyl ether is reacted with pyromellitic dianhydride and (XVII) maminobenzoyl-p-aminoanilide is reacted with pyromellitic dianhydride.ALSO:In the examples:-(X) isophthaloyl-m-aminoanilide is made by reacting m-nitroaniline with isophthaloyl chloride and reducing the resultant isophthaloyl-m-nitroanilide; (XI) p N:N1-bis(m-aminobenzoyl)-m-phenylene diamine is made by reacting m-nitrobenzoyl chloride with m-phenylene diamine and reducing the resultant N:N1-bis(m-nitrobenzyl)-m-phenylene diamine; (XII) p-aminobenzoyl-m-aminoanilide is made by reacting p-nitrobenzoyl chloride with m-nitroaniline and reducing the resultant p-nitrobenzoyl-m-nitroanilide; (XIII) bis(m-aminobenzoyl)-p : p1-diaminophenyl ether is made by reacting p : p1-diaminodiphenyl ether with m-nitrobenzoyl chloride and reducing the resultant bis(mnitrobenzoyl)- p : p1- diaminodiphenyl ether and (XVII) m-aminobenzoyl-p-amino-anilide is made by reacting m-nitrobenzoyl chloride with p-nitroaniline and reducing the resultant m-nitrobenzoyl-p-nitroanilide.
