    Abstract: Novel copolymers and terpolymers of the amide-imide type are prepared from tricarboxylic acid anhydride compounds, N,N'-diacylated diamines, N-acylated diamines, and primary diamines. These copolymers and terpolymers are useful for preparing injection molded articles of superior properties. A novel process for the manufacture of amide-imide copolymers and terpolymers is disclosed wherein the imide, imide-imide, amide, and amide-amide moieties incorporated into the polymer backbone can be controlled by acylating the amine functionality which is to form the amide and amide-amide moieties while reacting directly those diamines with a tricarboxylic anhydride compound which are intended to form the imide and imide-imide moieties.

    Abstract: A process for preparing high molecular weight solid polymers which process comprises reacting essentially equimolar amounts of a carbocyclic aromatic primary diamine and an acyl halide derivative of trimellitic anhydride under essentially anhydrous conditions and for a period of time and at a temperature controlled to produce a polymer with free carboxyl groups and amide groups available for further reaction. Also a process for preparing cured polyamide-imide polymers which comprises heating of the soluble polymers prepared as aforementioned at a temperature above 150*C sufficient to effectively and substantially convert such carboxyl and amide groups to imide groups and thereby produce a polyamide-imide which is insoluble in organic polar solvents.
