ABSTRACT:
Adhesion of fluoropolymer capstock layer to thermoplastic substrates such as polyvinyl chloride is achieved without the need for an intermediate adhesive layer while maintaining adequate impact resistance and processing properties by blending with the fluoropolymer a selected combination of acrylic polymers. The fluoropolymer-acrylic polymer blend includes a first acrylic polymer having a major methyl methacrylate monomeric component and a second acrylic polymer having a major ethyl methacrylate component.
