Abstract

1317321 Laminates INTERNATIONAL HARVESTER CO 13 April 1970 17360/70 Heading B5N [Also in Division C3] A polymerizable material consists essentially of a solid solution of substantially stoichiometric proportions of an aromatic diprimary amine having a primary amine basicity constant not exceeding 10<SP>-11</SP> in a benzophenone tetracarboxylic acid diester where R is alkyl or substituted alkyl. On heating in the absence of a solvent or water the solid solution may be converted to the corresponding polyamide-acid or directly to the polyimide but one stated to have a practically unlimited shelf-life. The solid solutions may be made by mixing the diamine with the molten diester until homogeneous or by reacting the corresponding dianhydride with excess esterifying agent and then adding and homogenizing the amine and removing excess esterifying agent. Specified diamines are 4,4<SP>1</SP>-diaminodiphenyl sulphone and 2,6-diaminopyridine. Solid solutions derived from specific combinations of at least two diamines which are the subject of Specification 1,317,322 are disclaimed. The solid solutions are stated to be low melting (e.g. 60‹ to 100‹C.), capable of being spray dried, and soluble in common low-boiling solvents, e.g. alcohols or ketones, and suitable for direct use by injection moulding, melt coating, film-coating or impregnation techniques. Uses.-Specified uses are: (a) Metal to metal adhesives using a mixture of the solid solution and aluminium powder knife-coated on to glass fabric as an adhesive layer; (b) Laminates of layers pre-impregnated with the solid solution; (c) Honeycomb structures from open-weave glass fabric pre-impregnated with the solid solution. The pre-impregnated fabric for all these applications may be prepared by solution-, melt- or knife-coating the fabric with the solid solution with or without additives or fillers; (d) As vehicles for ground or suspended pigments to prepare high-temperature resistant insulating coatings; and (e) Casting unpigmented films from solution or melt.
