Novel amino-substituted derivatives of 4-t-butylphthalic anhydride are used as monomers to produce novel polyimides with improved solubility characteristics. Increased solubility in organic solvents permits these polyimides to be used in coating applications where structurally similar polyimides could not otherwise be used.

Injection moldable copolymers are prepared from fully or partially acylated aromatic diamines and aromatic tricarboxylic anhydride compounds, aromatic dicarboxylic acids or mixtures of aromatic tricarboxylic acid anhydrides and aromatic dicarboxylic acids. These copolymers are useful for the preparation of injection molded articles and fibers.

Process of producing an amideimide polymer without using an acid having an acyl halide group which comprises reacting a composition comprising an aromatic diprimary amine and a tricarboxylic acid compound in an alcoholic solvent comprising an alkanol containing from 4 to 10 carbon atoms. In those cases where only diprimary aromatic amine is reacted, a tertiary amine is required. If desired, a glycol can be present.
