    Abstract: 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.

    Abstract translation: 聚酰亚胺在尼龙6共聚物中用作增强刚性骨架链段。 在第一个实施方案中,共聚物由聚酰亚胺制备,所述聚酰亚胺含有从其悬挂的酰化己内酰胺部分,其提供聚己内酰胺移植物的位点。 在第二个实施方案中,用酰基活化的己内酰胺环封端的聚酰亚胺低聚物允许形成包括聚酰亚胺加强段的嵌段己内酰胺共聚物。 聚酰亚胺/尼龙6共聚物具有优于尼龙6的性能,也可以用作相容剂。
