Abstract
A novel adhesive is described, consisting of a matrix-matrix polyblend of polymer components useful in an adhesive tie layer to bond incompatible polymer layers. The adhesives are a blend of the components making up the incompatible polymer layers themselves, or polymers substantially similar to these, and are melt processed to produce a matrix-matrix morphology with mechanical interlocking of the polymer components that is maintained upon cooling. Additives may be provided in one or both adhesive components to improve the cohesive strength of the adhesive formed by the mechanical interlocking.
