A comparative study on two methods for dissolving of powder lignocelluloses, derived from wood lignocelluloses and from short-length flax fibers, in DMAc/LiCl was carried out. It was shown that DPv values of the samples and lignin content significantly affected their solubility. The lower these values were, the better the solubility of the samples was. The(More)
A component, chemical and morphological composition of wood of the Howea fosteriana palm and the Cereus peruvians cactus and the wood stem of the Dracaena sanderiana was studied. The supramolecular structure and the physicochemical properties of cellulose samples which were extracted from the wood species were examined by wide-angle X-ray scattering,(More)
Adsorption properties of dressing cellulose materials with respect to surfactant antiseptics were studied. These antiseptics are a complex of the copolymer of N-vinylpyrrolidone and crotonic acid with dimethylbenzylalkylammonium chloride (a synthetic polymer with a wide spectrum of antimicrobial effect) and its low molecular weight analogue(More)
This project studies the dependence of the physical and chemical properties of powdered cellulose on their natural origin and conditions of preparation. We studied the effect of chemical composition and properties of the original native cellulose on the general characteristics of the powdered and microcrystalline cellulose obtained from arboreal and(More)
