Abstract

Linear polyamide-acids have the formula <FORM:1062435/C3/1> where R is a tetravalent aromatic radical having the four carbonyl groups attached to different ring carbons and R1 is <FORM:1062435/C3/2> They may be converted to polyimides of the formula <FORM:1062435/C3/3> by heating a solution thereof or by treatment with a monocarboxylic acid anhydride with or without a tertiary amine. The solutions, which may contain a pigment e.g. titanium dioxide may be used as coating compositions and converted to polyimide coatings in situ on a substrate. Several suitable dianhydrides and diamines for preparing the polymers are listed. Numerous applications of the polyimides are specified. Reference has been directed by the Comptroller to Specifications 898,651 and 928,717.ALSO:Solutions of linear polyamide-acids having the formula <FORM:1062435/B1-B2/1> where R is a tetravalent organic radical having the four carbonyl groups attached to different ring atoms and R1 is <FORM:1062435/B1-B2/2> (see Division C3), which solutions may contain a pigment e.g. 5 to 200% TiO2, are used to form coatings on various substrates e.g. metals, glass, cellulosic material, polymers or leather in the forms of sheets, wires, screens, foams or fabrics. The polyamide-acid coatings may be converted to polyimide coatings by heating a treatment with a dehydrating agent with or without a t-amine as described in Specifications 980,273 and 980,274. Wires coated in this way may be further coated with polymeric coatings such as silicones, polyamides, polyesters, tetrafluoroethylene and its copolymers with hexafluoropropylene, polyvinyl acetals and epoxy resins. Reference has been directed by the Comptroller to Specifications 898,651 and 928,717.
