Abstract

A composite article is provided which includes a blend component comprising a vinylidene fluoride containing fluoropolymer and a substantially non-vinylidene fluoride containing fluoropolymer, and a component including a substantially non-fluorinated polymer having pendant amine groups intimately bonded to the blend component. Increased adhesion is observed by a greater peel strength value between the blend component and a substantially non-vinylidene fluoride containing fluoropolymer when compared to a peel strength value between a substantially non-vinylidene fluoride containing fluoropolymer and the substantially non-fluorinated polymer having pendant amine groups.
