Abstract: The invention relates to the use of an impact-modified acrylic blend with a low level of fluoropolymer to achieve impact resistance and solvent resistance in a capstock formulation. Preferably the acrylic blend contains a methyl methacrylate-based acrylic polymer and polyvinylidene fluoride.

Abstract: The present invention relates to a microcomposite powder comprising particles from 1 um to 300 um of an electrically conductive product, which are coated with particles from 0.1 &mgr;m to 0.5 &mgr;m of a fluoropolymer. According to one advantageous form of the invention the microcomposite powder comprises a product (A) which is a polymer or an oligomer which can be dissolved with a solvent which is not a solvent for the fluoropolymer or for the electrically conductive product. The present invention also relates to objects consisting of this powder. These objects may be bipolar plates for fuel cells, or supercapacitor components.

Abstract: To introduce polar group by a simple and easy method without spoiling solvent-resistance and mechanical/thermal properties which fluorine type resin inherently possess to provide a fluorine type resin composition improved in adhesion. To provide an electrode structure for battery improved in adhesion between the electrode active material and the current collector by using the composition as a binder. Solution measure: partially denatured fluorine type resin (B′) obtained by partial dehydrogenfluoride reaction and oxidation reaction is mixed to at least one fluorine type resin (A) at a weight ratio of (A/B′) of 30/70 to 99/1.

Abstract: Especially for electrodes, there is provided a structure successively comprising a layer of a metal L1, a fluoro primer L2 and a layer of a fluoro polymer L3 in which the flouro primer L2 is derived from a fluoro polymer chemically modified by a partial dehydrofluorination with a base followed by an oxidation step, especially with H2O2. According to one specific form, the structure is an electrode of a lithium-ion battery in which the metal L1 is the collector and the fluoro polymer L3, which has a high content of carbon and/or oxides, is the electroactive layer thereof.

Abstract: A surface modified, U.V. stabilized opaque polyvinyl chloride resin article and process for making same is described. The article includes a white pigment, such as titanium dioxide, in low amounts. The modified surface is substantially free of residual stabilizer and solvent, and its appearance and degree of surface perfection is substantially the same as an unmodified side of the article.The process of the invention is characterized by the steps of immersing the polyvinyl chloride article is immersed in a suitable liquid media, then contacted with a solution of an ultraviolet light stabilizer in a suitable organic solvent, and residual stabilizer and solvent are displaced in situ, i.e. in a non-evaporative environment without contacting the air.
