<p>Multi-layered thermoplastic structures comprising a layer of a vinyl or vinylidene fluoride polymer bonded to a layer of an alpha-olefin polymer with the joint aid of a vinyl acetate polymer and a copolymer of ethylene and vinyl acetate. The multi-layered thermoplastic structures can be in the form of films, sheets, plates or tubes which can be used in the field of protection from corrosion or ultra-violet rays.</p> |
