  • Patent number: 11952483
    Abstract: A resin composition including: at least one resin ingredient selected from the group made of a resin (A) having a side chain (a) containing a hydrogen-bonding cross-linking moiety with a carbonyl-containing group and/or a nitrogen-containing heterocycle and having a glass transition point of 25° C. or lower, and a resin (B) containing a hydrogen-bonding cross-linking moiety and a covalent-bonding cross-linking moiety in a side chain and having a glass transition point of 25° C. or lower, wherein both the resin (A) and the resin (B) are a reaction product of a cross-linking agent with a maleic anhydride-modified thermoplastic resin having a melting point of 68° C. to 134° C. and a maleation rate of 0.5 to 2.5% by mass.
    Type: Grant

  • Publication number: 20210139704
    Abstract: Disclosed is a method for producing a paraffin wax, the method including a step of mixing an unrefined wax containing normal paraffin with a solvent of dipole term (?p) is 4 to 8 and of hydrogen bonding term (?h) is 3 to 10 of the Hansen Solubility Parameters, and obtaining a mixed liquid; and a step of separating a solid material from the mixed liquid and obtaining a paraffin wax in which the normal paraffin concentration is higher.

  • Patent number: 8900350
    Abstract: One aspect of the present teachings includes a separation membrane arranged in a hollow case. A particular component concentration chamber and a particular component dilution chamber are arranged in series in the hollow case. The particular component concentration chamber is capable of increasing concentration of the particular component by allowing permeation of the particular gas through the separation membrane. The particular component dilution chamber is capable of increasing concentration of the particular component by not allowing permeation of the particular gas through the separation membrane. The particular component concentration chamber and the particular component dilution chamber are configured such that only a gas containing the particular component and permeated through the separation membrane or only a gas containing the particular component not permeated through the separation membrane in one of the chambers disposed on an upstream side (i.e.
