Publication number: 20230253593Abstract: A layered film is prepared by layering a substrate layer, a first layer containing an acid-modified olefin-based resin, a second layer containing a cyclic olefin-based resin, and an ion-exchange resin-containing layer containing an ion-exchange resin in this order. Each of the second layer and the first layer may be a layer formed by coating. The average thickness of the second layer may be 30 ?m or less. A membrane electrode assembly of a solid polymer-type fuel battery may be produced by releasing a layer other than the ion-exchange resin-containing layer from the layered film. The layered film does not contain a component having a large environmental load even when the release layer is formed of the cyclic olefin-based resin, firmly attaches to a substrate, and can be released smoothly from the ion-exchange resin-containing layer serving as a transfer medium.Type: ApplicationFiled: March 19, 2021Publication date: August 10, 2023Applicant: Daicel CorporationInventors: Kazuyuki OKADA, Kanae NISHIMURA, Takumi SHINMURA

Patent number: 10622658Abstract: A release layer of a release film for producing a membrane electrode assembly of a polymer electrolyte fuel cell comprises a cyclic olefin polymer comprising an olefin unit having a C3-10alkyl group as a side chain thereof. The release layer may have a glass transition temperature of about 210 to 350° C. The release layer may have a transition point of a dynamic storage modulus E? in a range from ?50 to 100° C. An ion exchange layer comprising an ion exchange polymer may be laminated on the release layer of the release film by a roll-to-roll processing to produce a laminate. The release film may be separated from the laminate to give the membrane electrode assembly. The release film achieves improved production of a membrane electrode assembly (an electrolyte membrane and/or an electrode membrane) of a polymer electrolyte fuel cell.Type: GrantFiled: November 4, 2014Date of Patent: April 14, 2020Assignees: DAICEL CORPORATION, DAICEL VALUE COATING LTD.Inventors: Hiroshi Onomichi, Katsuhiko Sumita, Yoshimichi Okano, Kanae Nishimura, Kazuyuki Okada, Takayuki Yaegashi, Ken Suzuki

Patent number: 10355298Abstract: A polymer film comprises a polymer composition containing (A) a cyclic olefin polymer and (B) a chlorine-containing polymer. The chlorine-containing polymer (B) may comprise a vinylidene chloride-series polymer. The cyclic olefin polymer (A) may comprise a cyclic olefin copolymer. The ratio of the chlorine-containing polymer (B) relative to 100 parts by weight of the cyclic olefin polymer (A) may be 0.5 to 60 parts by weight. The film has a moderate releasability from an electrolyte membrane and an electrode membrane of a polymer electrolyte fuel cell and a moderate adhesion to the electrolyte membrane and the electrode membrane and can adhere to a commonly-used substrate film without interposition of an adhesive layer such as an easily adhesive layer. The film is thus suitable as a release film for producing a membrane electrode assembly of a polymer electrolyte fuel cell.Type: GrantFiled: April 30, 2015Date of Patent: July 16, 2019Assignees: DAICEL VALUE COATING LTD., DAICEL CORPORATIONInventors: Kazuyuki Okada, Kanae Nishimura

Patent number: 5947127Abstract: A filter rod is produced by adding a water-soluble polymer in the form of an aqueous solution or dispersion, or in a particulate form, to a tow of cellulose ester fiber, with the amount of any water used being controlled within 25 parts by weight relative to 100 parts by weight of the tow, and wrapping the treated tow in wrapping paper. The water contained in the filter rod is removed or the particulate water-soluble polymer is melted by heating to bond the fiber to provide a tobacco filter. The proportion of the water-soluble polymer is 0.5 to 30 parts by weight to 100 parts by weight of the tow. To reduce the amount of water relative to the tow, a hot-melt adhesive water-soluble polymer may be employed. As the amount of water added to the tow is thus decreased, the tow can be smoothly wrapped up even at a high speed so that filter productivity is improved. This tobacco filter is highly wet-disintegratable and, hence, contributes to mitigation of the environmental pollution.Type: GrantFiled: May 16, 1997Date of Patent: September 7, 1999Assignees: Daicel Chemical Industries, Ltd., Japan Tobacco, Inc.Inventors: Hitoshi Tsugaya, Hiroki Taniguchi, Nobuyuki Oji, Kanae Nishimura

Patent number: 5758669Abstract: Water disintegratability of a tobacco filter is improved by incorporating a super absorbent resin into a tobacco smoke filter medium in a tobacco filter comprising a main constitutive element of the tobacco smoke filter medium, and a water-soluble polymer as a binder for shaping the constitutive element. The constitutive element includes particulate or fibrous cellulose and cellulose esters (e.g. cellulose acetate). The water-absorption ratio of the super absorbent resin is about 10 to 1,000 times, and the amount of the resin is about 0.05 to 50 parts by weight relative to 100 parts by weight of the main constitutive element of the tobacco smoke filter medium.Type: GrantFiled: October 4, 1996Date of Patent: June 2, 1998Assignee: Daicel Chemical Industries, LimitedInventors: Hiroki Taniguchi, Kanae Nishimura
