Abstract: 1,271,399. Polyamide acid solutions. STANDARD OIL CO. 30 July, 1969 [6 Aug., 1968], No. 38267/69. Heading C3R. The viscosity of a solution containing 15 to 50 wt. per cent of a polyamide-acid of trimellitic acid and an aromatic diamine in a solvent comprising an N-alkyl amide, a phenol or a sulphoxide-group-containing solvent is reduced by heating the solution at 70 to 150 C. in the presence of 1 to 10 wt. per cent of water. The solution may be obtained by preparing the polymer in a specified solvent or in a different solvent, e.g. a 165 to 235 C. semi-refined coal tar distillate, or by dissolving a solid polymer. The polymer may have been prepared from the acid chloride and treated with propylene oxide to scavenge HCl. The process is stated to improve the storage stability of wire enamel solutions and may be applied to an already aged enamel.
