摘要: 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 adhesive or tie layer. The structures exhibit strong adhesion but can easily separated (for recycling, etc.) once integrity either layer is impaired. cracked polybutylene, nylon-6, nylon-12, copolyetherester polyvinyl chloride.
