Abstract

Polyester (I) having terminal carboxylic acid and/or anhydride gps. are obtd. from (1) a polyester of formula: HO(-R-O-CO-R'-CO-O)n-ROH (I) in which n = 1 to 20, R = an alkylene, unsatd. alkylene, alkylene ether, aromatic ether-alkyl or alkylene-cycloalkylene- alkylene-chain and R' = an alkylene gp-, aromatic ring, unsatd. alkylene-, alkylene ether- or aromatic ether alkylene-chain, and (2) a polyfunctional carboxylic acid or its anhydride, e.g. trimellitic acid, benzophenone tetracarboxylic acid, pyromellitic acid or an anhydride of such acids. The polyesters are useful for hardening epoxy resins, e.g. in powder coating methods, or for hardening conventional polyester resins.
