  • Publication number: 20240336816
    Abstract: The present invention is to address the problem of providing an electrically peelable adhesive product having excellent electrical peelability even under conditions where the adhesive product is exposed to high temperature conditions over a long period of time. The problem is solved by an electrically peelable adhesive composition comprising an acrylic polymer, an ionic liquid and an alkyl ether of a polyethylene glycol, wherein a content of the ionic liquid is more than 30 parts by weight and 90 parts by weight or less relative to 100 parts by weight of the acrylic polymer and a content of the alkyl ether of the polyethylene glycol is 5 parts by weight to 45 parts by weight relative to 100 parts by weight of the acrylic polymer.

  • Publication number: 20220195259
    Abstract: The present invention has an object of obtaining an electrically peelable adhesive product that is strong in adhesibility when used, is excellent in peelability even though a low voltage is applied, and does not leave much adhesive deposit after being peeled. The present invention achieves the above object by virtue of an electrically peelable adhesive composition contained in the adhesive product, the adhesive composition comprising an acrylic polymer, an ionic liquid having an ionic conductivity of 10?4 S/cm or more to 10?2 S/cm or less, and an alkyl ether of a polyethylene glycol, and containing 5 parts by weight or more to 30 parts by weight or less of the ionic liquid and of the alkyl ether of the polyethylene glycol with respect to 100 parts by weight of the acrylic polymer.

  • Patent number: 5185217
    Abstract: A relatively displacing apparatus including a movable member and a stationary member which has a coating layer disposed adjacent to the movable member, formed by flame spray coating and including at least one selected from the group consisting of hexagonal system boron nitride and ceric oxide. Since the coating layer is easily machined with the movable member, the coating layer comes to have a surface generated by machining with the movable member and the clearance between the movable member and the stationary member is made zero (0) substantially when the movable member and the stationary member displace relatively at a high temperature. Thus, the efficiency of the relatively displacing apparatus has improved. In addition, since the coating layer has a high thermal shock resistance, the durability of the relatively displacing apparatus has improved.

  • Patent number: 5096593
    Abstract: The separation material for separating and recovering a blood coagulation factor comprises a porous matrix having linked thereon one or more ligands each consisting of a radical exhibiting an affinity for the blood coagulation factor to be recovered, said matrix having a specific surface area of at least 1.5 m.sup.2 per milliliter of the separation material with respect to pores having diameters of at least 0.1 .mu.m and being derived from a porous particulate material having an exclusion limit molecular weight of at least 1.5.times.1.sup.6 as determined with polyethylene glycol. The separation material is prepared by the process steps of subjecting a porous particulate material having an exclusion limit molecular weight of at least 1.5.times.10.sup.

  • Patent number: 4948814
    Abstract: A novel ion exchanger useful for universal ion-exchange purposes and, in particular, for ion exchanger for ion-exchange chromatography is proposed, said novel ion exchanger being obtained by introducing radicals of one or more ion-exchangeable groups into cross-linked glucomannan beads by a chemical treatment thereof. Such ion exchanger beads are superior in the compressive strength and permit a high flow rate of the liquid to be subjected to ion exchange through an exchange column packed with them.
