ABSTRACT:
A coextruded multi-layer structure may be formed by coextruding a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon (a polyketone polymer) with an other thermoplastic polymer, without the use of an adhesive or tie layer. The multi-layer structures exhibit strong adhesion but can be easily separated (for recycling, etc.) once the integrity of either layer is impaired. The other thermoplastic polymer is a cracked polybutylene, nylon-6, nylon-12, a copolyetherester polymer, or polyvinyl chloride.
