ABSTRACT:
Addition polyimide resins having improved thermo-oxidative stability and enhanced processability are prepared by the reaction of a mixture of monomers comprising a non-planar polyphenyl diamine (a), a diester of tetracarboxylic acid or the corresponding dianhydride (b) and an end-capping agent (c), or a diamine (d), a non-planar polyphenyl diester or dianhydride of a tetracarboxylic acid (e) and an end-capping agent (c).
