Abstract

Polyamideimide resins having the formula (I) ##STR1## in which repeating units are bound in a head to tail or head to head manner, R is at least two divalent groups selected from the group consisting of ##STR2## (cis-, trans- conformational mixture) wherein one divalent group is ##STR3## group in a PAI molecule, produced by introducing isophorone diamine into the conventional aromatic polyamideimide resins.
