Abstract: An optically brightened and stabilized polyamide contains (A) a derivative of 1:4-bisstyrylbenzene having free carboxy groups, carboxylic acid ester groups, carboxylic acid amide groups and/or nitrile groups combined with both terminal phenyl radicals in the styryl groups as claimed in the parent Specification, and (B) an alkali or alkaline earth metal salt of phosphorous acid. The polyamides may contain additionally Ti(III) and cerium (III) salts, e.g. cerium (III) chloride and acetate and titanium (III) chloride hexahydrate, sulphate hexahydrate and acetate hexahydrate. Many polyamides and 1:4-bis-styryl benzene derivatives are specified. Specified phosphorus acid salts are sodium hydrogen phosphite and barium hydrogen phosphite. Examples (1) and (2) describe the addition to polyhexamethylene adipamide of:-(1) sodium phosphite pentahydrate, 1:4-bis(p-cyanostyryl)-benzene and titanium trichloride and (2) 1:4-bis-(p-carboxymethyl-styryl) benzene, sodium phosphite pentahydrate and titanium trichloride hexahydrate whist Examples (3) and (4) describe the addition to polycaprolactam of:-(3) the morpholide of 1:4-bis(p-carboxystyryl)-benzene, sodium phosphite and titanium trichloride hexahydrate and (4) sodium phosphite, 1:4-bis-(p-cyanostyryl) benzene and cerium trichloride heptahydrate.
