| titleOfInvention | Chitosan condensation products, their production and use |
| abstract | (57) [Summary] A chitosan condensation product is obtained by combining chitosan and a sulfite addition compound HOCRR'SO 3 A (wherein each of R and R 'is independently a hydrogen atom, or R is a hydrogen atom. R ′ is an optionally substituted linear or branched, saturated or unsaturated hydrocarbon group having up to 10 carbon atoms or an optionally substituted alicyclic, aromatic carbocyclic ring Is a formula or heterocyclic ring, or R is a CH 3 group, R ′ is an optionally substituted primary alkyl group, or R and R ′ are both optionally substituted Alicyclic or heterocyclic rings, and A is an alkali metal or ammonium ion). The condensation product / polymer is an anionic polyelectrolyte and forms a stable anionic solution in water at neutral pH. Such solutions can be mixed with other water-soluble anionic polyelectrolytes, especially sodium alginate, to form highly mixed mixtures or blends, from which films, fibers, powders, sponges, gels and foams are formed. Can be manufactured. From the condensation products in these films, fibers, powders, sponges, gels and foams, chitosan can be regenerated by acid or alkali treatment during or after their production. Also, the solubility of the condensation products opens the way to new methods for extracting chitosan from chitin / calcium carbonate mixtures. |
