    • A multi-layer article comprises a substantially non-fluorinated layer, and a fluorinated layer of fluoropolymer comprising interpolymerized monomeric units derived from one or more of hexafluoropropylene and tetrafluoroethylene monomers, one or more non-fluorinated olefinically unsaturated monomer, and substantially no vinylidene fluoride monomer. The multi-layer article further comprises an aliphatic di-, or polyamine which provides increased adhesion between the layers as compared to a multi-layer article not containing the aliphatic di-, or polyamine. The multi-layer article can be prepared by mixing the aliphatic di-, or polyamine into the substantially non-fluorinated polymeric material, or by applying the aliphatic di-, or polyamine to a surface of one or more of the substantially non-fluorinated polymeric material or the fluoropolymer, and thereafter preparing a multi-layer article.
    • 多层制品包括基本上非氟化层和含氟聚合物的氟化层,其包含衍生自六氟丙烯和四氟乙烯单体中的一种或多种的共聚单体单元,一种或多种非氟化烯属不饱和单体,基本上不含偏二氟乙烯单体 。 与不含脂肪族二胺或多胺的多层制品相比,多层制品还包含脂族二胺或多胺,其提供层之间增加的粘合性。 多层制品可以通过将脂族二胺或多胺混合到基本上非氟化的聚合物材料中,或通过将脂族二胺或多胺施用到一种或多种基本上非氟化的聚合物 材料或含氟聚合物,然后制备多层制品。
