Cellulose Patents (Class 524/35)
  • Patent number: 8829110
    Abstract: A new approach is conceived for the development of sustainable biomaterials comprising nanocrystalline cellulose (NCC) and polylactic acid (PLA) nanocomposites. The invention deals with advancing a method based on in situ ring opening polymerization of L-lactide in the presence of NCC particles to form NCC-PLA supramolecular nanocomposite materials. This material is hydrophobic and compatible with a wide range of synthetic and natural polymers. NCC-PLA nanocomposites have enhanced functionality (e.g. gas barrier), rheological and mechanical performance, as well as dimensional stability (i.e. less hygroexpansivity) relative to PLA. They are made from entirely renewable resources, and are potentially biocompatible as well as recyclable. NCC-PLA supramolecular nanocomposites can be suspended in most organic solvents or dried to form a solid substance. They can be processed using conventional polymer processing techniques to develop 3-dimensional structures, or spun into fibers, yarns or filaments.

  • Publication number: 20140235762
    Abstract: Disclosed are a water-dispersible halogen-capping polyalkylacrylate, a vinyl chloride-based block copolymer and a method for preparing the same. By using the water-dispersible halogen-capping polyalkylacrylate derivative as a chain transfer agent for polymerization of a vinyl chloride-based monomer, it is possible to obtain effects such as reduction of coagulation of particles and adhesion of particles to a reactor wall, improvement in reaction efficiency and polydispersity index, and prevention of yellowing.

Specifically, the SAPs according to the present invention which initially spontaneous assemble, surprisingly form stable solid scaffolds upon exposure to neutral pH buffer. Further these SAPs allow adhesion, proliferation and differentiation of murine and human neural stem cells and have self-healing propensity. They also did not exert toxic effects in the central nervous system, can stop bleeding and foster nervous regeneration.

  • Publication number: 20140061554
    Abstract: A composite material comprising 10-98 wt. % of a bio-based particulate or fibrous filler and at least 2 wt. % of a polyester derived from an aliphatic polyalcohol with 2-15 carbon atoms and a polyacid, wherein the polyacid comprises at least 10 wt. % of tricarboxylic acid. Preferably, the filler is in the form of particles, fibers, and/or random or non-random layers. A plant-based filler may be used, in particular a cellulosic or lignocellulosic material, more in particular one or more materials selected from wood chips, wood flakes, sawdust, pulp, e.g., pulp of (recycled) paper or other fiber pulp, and plant-derived fibers such as cotton, linen, flax, and hemp. An animal-derived filler, in particular an animal-derived fiber such as wool, hair, silk, or feathers may also be used. Preferably the polyalcohol is selected from one or more of glycerol, sorbitol, xylitol, mannitol, 1,2-propane diol, 1,3-propane diol, and 1,2-ethane diol, in particular glycerol.
