摘要:
The invention relates to novel cellulose derivatives comprising a ligand capable of forming a complex with a polyvalent metal ion. The invention further pertains to a process of preparing such cellulose derivatives.
摘要:
A coating composition is composed of a water-soluble polysaccharide composition comprising at least one hydrophobic group selected from aryl, alkyl, alkenyl, aralkyl and mixtures thereof and at least one quaternary ammonium salt group, both connected to a polysaccharide backbone by covalent bonds. This coating is used for improving the leveling of waterborne paints.
摘要:
The instant invention relates to primary coating compositions that comprises a cationic polysaccharide, to be applied on a hydrophobic surface before a subsequent application of a polar or water based coating composition, such a as a paint or an adhesive.
摘要:
The preparation of a slurry so as to exhibit no strong alkalinity not only needs a strict pH control, but also needs once dispersing a positive electrode material in water and the operation of drying after the treatment, and other operations, thereby leading to the complication of the operations and a decrease in the yield. In consideration of the above-mentioned problems, the present invention provides a method for producing a positive electrode plate for a lithium ion rechargeable battery, which exhibits less complication of the operations and less decrease in the yield and can prevent the gelation of a positive electrode material slurry. The above-mentioned problems can be solved by a positive electrode for a lithium ion rechargeable battery containing a positive electrode active material capable of absorbing/desorbing lithium ions, a nitrile group-containing polymer, and a binder.
