PURPOSE:To improve the frictional and wear characteristics, by incorporating an aromatic polyimide resin into a non-crystalline, thermoplastic aromatic polyamide-imide resin which has excellent heat stability, etc., and contains a diphenyl ether linkage as its essential component. CONSTITUTION:60-99wt% non-crystalline, thermoplastic aromatic polyamide- imide resin (A) containing a diamine residue or diisocyanate residue consisting of 0-100mol% unit of formula I, 80-0mol% unit of formula II, and 60-0mol% unit of formula III or IV (where R1 is an alkyl of 1-4C; R2 is an alkyl of 1-4C or a halogen; X is -SO2-, -CO-, etc.; a is 1-25; b is 0 or 1-4; c is 0 or 1-2) (total residue being 100mol%) is incorporated with 40-1wt% aromatic polyimide resin (B) containing the repeating units shown by formula V (where Y is a direct linkage, -O-, etc,; Ar is an aromatic diamine residue or isocyanate residue) as its principal structural unit.
