    摘要: The disclosure relates to a novel process for functionalizing NCC, a method for producing amine-cured epoxy-based nanocomposites through the use of said functionalized NCC, and nanocomposites thereof. The process for functionalizating NCC comprises providing a mixture of NCC and one or more monomers. The mixture is suitable for free radical polymerization and the monomer is cross-linkable with epoxy and is aqueous soluble. The polymerization takes place in the presence of a free radical initiator and oxygen is purged from the mixture and the initiator solution. The epoxy-based nanocomposite is produced by mixing the funtionalized NCC with an amine-curable epoxy resin and a hardener, in a solvent, and allowing the mixture to cure.

    摘要: There is disclosed a method for the manufacture of a crosslinked superabsorbent polymer material. There is further disclosed a crosslinked superabsorbent polymer material manufactured with the method. Using the new polymer material the previously used undesired chemistry based on polymerization of acrylamide is avoided and the less desired chemistry based on polymerization of on acrylic acid is significantly reduced. In addition the present polymer material is renewable. In contrast to the state of the art lignin does not have to be removed from the hydrolysate, so that energy, time and cost are saved and inexpensive raw materials and inexpensive process streams can be used. Lignin in the polymer material gives stronger bindings resulting in improved mechanical properties of the material. The presence of lignin further makes it possible to modify the hydrophilicity of the crosslinked polymer material. The raw materials are typically not valuable foodstuffs.
