ABSTRACT:
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.
