Preparation of polymers and reactive prepolymers by the aminolysis of acylbis(hexanelactams)

Abstract

The aminolysis of N,N'-isophthaloyl and N,N'-terephthaloyl-bis(6-hexanelactam) with aliphatic diamines was used in the preparation of semiaromatic polyamides, in the extension of polymer chains and in the preparation of N,N'-[poly(oxyethylene)di(carbamoylbenzoyl)]bis(6-hexanelactams) under mild conditions (50-80 °C).
