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.

Multilayer polyketone structures

Conductive polymer compositions comprising a linear alternating polyketone polymer and a conductive carbon fiber exhibit conductive properties at low additive loadings.

Conductive polyketone polymers

Blends of (a) a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon and (b) a maleated polyolefin polymer exhibit improved properties of thermal stability, impact resistance as better processability.

Polymer blend

Laminated billets are made by extruding a plurality of sheets, cooling and stacking said sheets to form a stack, laminating a portion of said stack using radio frequency radiation, cutting out at least the laminated portion from the stack and returning the resulting individual webs to their respective sheet extrusion process.
