  • Patent number: 11898009
    Abstract: A flexible electronic device containing a polyimide film exhibiting excellent C-V characteristics. The polyimide film is a film that shows a maximum gradient of 0.005/V or more in a capacitance-voltage measurement of a laminate in which a polyimide film having a film thickness of 0.75 ?m is formed on a silicon wafer having a resistance value of 4 ?cm; the maximum gradient meaning a maximum value of an absolute value of a gradient in a normalized capacity-voltage curve during a third scan of forward direction scans; a capacity-voltage curve being measured by applying a direct current voltage is to the polyimide film with respect to the silicon wafer between a lowest voltage V1 and a highest voltage V2, and measuring capacitance while the direct current voltage is scanned in a forward direction and scanned in a negative direction; the normalized capacity-voltage curve being normalized so that the capacity at the lowest voltage V1 is 1.

  • Publication number: 20110039999
    Abstract: The present invention relates to a process for the continuous production of a biodegradable polyester based on aliphatic or aliphatic and aromatic dicarboxylic acids and on aliphatic dihydroxy compounds, where a mixture composed of the aliphatic dihydroxy compounds, of the aliphatic and aromatic dicarboxylic acids, and, if appropriate, of further comonomers (component C) is mixed, without addition of a catalyst, to give a paste, or, as an alternative, the liquid esters of the dicarboxylic acids are fed into the system, as also are the dihydroxy compound and, if appropriate, further comonomers, without addition of any catalyst, and i) in a first stage, this mixture, together with the entire amount or with a portion of the catalyst, is continuously esterified or, respectively, transesterified; ii) in a second stage, the transesterification or, respectively, esterification product obtained in i) is continuously precondensed if appropriate with the remaining amount of catalyst to an intrinsic viscosity of from

  • Publication number: 20100323112
    Abstract: A coating composition made with fumed silica, a hydroxy-functional amide compound, and a volatile organic portion, wherein the volatile organic portion comprises about 1 to about 7% by weight of a first volatile organic liquid or combination of first volatile organic liquids (i) having an evaporation rate less than or equal to 0.1 and (ii) in which the hydroxy-functional amide compound is insoluble has improved sag resistance. Sag resistance may be further improved by including in the volatile organic portion at least about 10% by weight of a second volatile organic liquid having an evaporation rate greater than or equal to about 2.0. Finally, flow and leveling of the coating (resulting in reduced orange peel and smoother appearance) can be improved, without worsening sag resistance, by including from about 5% to about 60% by weight of a dispersant for the fumed silica based on weight of fumed silica, wherein the dispersant is soluble in the first volatile organic liquid or liquids.

  • Publication number: 20100323161
    Abstract: The present invention is related to a polyimide copper clad laminate and the process of making the same. The laminate comprises a layer of polyimide and a layer of copper foil, wherein the polyimide layer is made from a polyimide precursor comprising a diamine monomer, a dianhydride monomer, an organic solvent and a silane coupling agent having one or more organic functional groups, and the copper foil is a smooth copper foil. The polyimide layer of the present invention provides high transparency, good dimensional stability, good mechanical properties and good adhesion to the copper foil.

  • Publication number: 20090218059
    Abstract: A solution with a salt-sensitive polymer binder for use in fibrous webs, where the binder contains a copolymer comprising repeat units derived from butyl acrylate, methyl methacrylate and amino functionalized alkyl acrylate or methacrylate or amino functionalized alkyl acrylamide or methacrylamide optionally including monomers such as vinyl acetate and/or vinyl acetate/ethylene. The binder solution is prepared by emulsion-polymerizing a copolymer and then neutralizing the copolymer with acid to make it water soluble. The binders are particularly suitable for strengthening nonwoven fibrous webs in disposable articles such as wet-wipes, personal care products, diapers, and the like and retain their salt-sensitivity with or without divalent metal scavengers.
