Polyimides serve as reinforcing rigid-backbone segments in nylon 6 copolymers. In a first embodiment, the copolymers are prepared from polyimides containing acylated caprolactam moieties pendant therefrom which provide sites for polycaprolactam grafts. In a second embodiment, polyimide oligomers end-capped with acyl-activated caprolactam rings permit the formation of block caprolactam copolymers that include polyimide reinforcing segments. The polyimide/nylon 6 copolymers have properties superior to those of nylon 6 and can also serve as compatibilizing agents.
