Abstract: Secondary amine-terminated aromatic oligomers are prepared by conventional reactions for the formation of such polymers as polyimides, polyethersulfones and polyetherketones, using such compounds as methylamino or phenylamino anilines or phenols as endcapping agents. The secondary amine-terminated oligomers may be reacted with cyclic polycarbonate oligomers to prepare copolyurethanecarbonates which are useful as engineering thermoplastics.
