  • Patent number: 10030093
    Abstract: A cellulose nanofiber (CNF) powder of the present invention contains cellulose nanofibers, and a hydrophobic polymer that is chemically bonded to at least some of the —OH groups of the cellulose nanofibers. The CNF powder has the ability to be dispersed in water and to return to a powder form again when an aqueous dispersion of the CNF powder is dried. The distance between the fibers in the CNF powder in a dry state is 3 nm or more, and preferably 8 to 12 nm. Since the distance between the fibers in the conventional cellulose nanofibers is about 1 nm, the present invention reduces the Van der Waals force between the fibers (i.e., the force of attraction between the fibers) to one millionth of that of the conventional cellulose nanofibers. Thus, the present invention provides the CNF powder that can be used in a powder form, and that can also be reversibly changed between a powder state and a dispersed state in water, and a method for producing the CNF powder.

    Abstract: To provide an adhesive composition which can effectively improve the thermal-peeling-easy properties and the adhesion properties at low temperature at the same time. An adhesive composition comprising a crystalline polymer which comprises polyol units formed from a crystalline polyol as repeating units in the molecule, and a tackifying polymer compatible with said crystalline polymer at a temperature higher than the melting point of said crystalline polymer, wherein the tackifying polymer has an alkyl group with 4 to 8 carbon atoms and a carboxyl group in the molecule, a content of the monomeric units having the alkyl group with 4 to 8 carbon atoms (repeating units derived from a starting monomer having the alkyl group) is 60 to 99 mole % of the whole monomeric units of the tackifying polymer, and the alkyl group includes a butyl group.
