Abstract
A multi-layer article comprises a fluoropolymer layer comprising interpolymerized units derived from vinylidene fluoride, and a melt-processable, substantially non-fluorinated polymer layer comprising a polyamide, polyimide, polyurethane, or a carboxyl, anhydride, or imide functionalized polyolefin. The non-fluorinated polymer layer further contains an aliphatic di-, or polyamine which provides increased adhesion between the fluoropolymer layer and the non-fluorinated polymer layer.
