Abstract
Multilayer polyketone compositions are presented. These compositions have at least one layer of polyketone, at least one layer of a polyamide having a lengthy aliphatic chain segment and a tielayer of a polyamide having a short aliphatic chain segment, a polyamide-AABB portion, a polyamide having a lengthy aliphatic chain segment, and preferably residual polyamide monomer. Processes for making these composites are also presented. In another embodiment of the invention, the tielayer is a polyamide monomer.
