Abstract: This invention provides a method of bonding substantially non-fluorinated polymeric material to a fluoropolymer utilizing a bonding composition comprising primary or secondary di- or poly-amine and a melt-processable, substantantially non-fluorinated component. Multi-layer articles and composite constructions, including retroreflective sheeting and fuel line hoses, made of a fluoropolymer layer and a substantially non-fluorinated layer are also provided.

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.

Abstract: A composite article is provided which includes a blend component having first and second surfaces and a substantially non-fluorinated polymer component adhered to the first surface of the blend component, wherein the substantially non-fluorinated polymer component has an exposed surface. The blend component includes a first hydrogen containing fluoropolymer; and a substantially non-fluorinated polymer having one or more pendant primary or secondary amine groups. Increased adhesion is observed by a peel strength value between the blend component and the substantially non-fluorinated polymer component when compared to a peel strength value between a component consisting of a fluoropolymer and a component consisting of a substantially non-fluorinated polymer having pendant primary or secondary amine groups.

Abstract: Briefly, in one aspect, this invention provides a melt-processable composition comprising, in admixture: (1) one or more melt-processable thermoplastic hydrocarbon polymers as the major component of the composition by weight, and, as a minor component of the composition by weight, (2) an effective amount of a chemically-resistant, fluoropolymer process aid to improve the processability of the composition and (3) one or more poly(oxyalkylene) polymers.

Abstract: This invention provides a melt-processable conductive fluoroplastic composition comprising a melt-processable, thermoplastic fluoropolymer component of interpolymerized units comprising those derived from vinylidene fluoride, a conductive particulate component comprising conductive carbon black particles, and a hydrocarbon polymer component. The composition is useful for making, for example by melt-processing, conductive shaped articles including tubing.

Abstract: This invention provides a melt-processable fluoroplastic composition comprising a blend of a melt-processable thermoplastic fluoropolymer component of interpolymerized units derived from vinylidene fluoride and an ethylenically-unsaturated, copolymerizable, fluorinated comonomer, and a hydrocarbon polymer component comprising a poller of ethylene or propylene. The composition is useful for making shaped articles including tubing or film.
