ABSTRACT:
It is herein disclosed a composite system consisting essentially of a polyketone polymer and an aminated polyolefin, produced by reacting a polyolefin with excess diamine to form an imide with a free primary amine, and causing the primary amine to react with a polyketone chain to form a pyrrole. These reactions can occur during inter alia a co-extrusion hot coating application or blending process. In all cases, compatibilization is achieved by the formation of polyketone/polyolefin graft copolymers at the interface of the polymers.
