Abstract
Structures with multiple polymeric layers comprising a vinylidene fluoride polymer layer bonded to a polar polymer layer by the use of a polymeric adhesive comprising a vinyl acetate polymer. These structures are characterized in that the product of the weight content of vinyl acetate of the polymeric adhesive, expressed in percent, and its dynamic viscosity at 100° C. and 1 s-1, expressed in kPa s, is greater than 1.4×103. The structures with multiple polymeric layers can take the form of films, sheets, panels, tubes or hollow bodies which can be employed particularly in the field of protection against corrosion or ultraviolet rays.
