摘要： A laminated film includes a polylactic acid-based resin layer and one or more acetylated hyaluronic acid layers laminated on a side of the polylactic acid-based resin layer, is highly flexible and easy to handle and, when stuck to an adherend with curved surface, the laminated film has excellent followability, adhesiveness and coating properties to the adherend, since the acetylated hyaluronic acid layer(s) can be removed easily with an aqueous solution from the polylactic acid-based resin layer in a thin film shape. The acetylated hyaluronic acid and the polylactic acid-based resin are biodegradable and, therefore, the laminated film is highly compatible with skin and organs such as visceral organs. The laminated film is optimally usable as a dermal material for external application such as a wound coating material, an adhesion inhibitor and skin care articles.

摘要： The invention relates to a dry or slurry process to prepare phosphate-crosslinked cellulose ethers from a cellulose starting material comprising the steps of adding an alkalizing agent to the cellulose starting material to achieve mercerization, adding an ethehfying agent to the reaction mixture to achieve etherification of the cellulose, and adding a crosslinking agent to the reaction mixture to achieve crosslinking of the cellulose, wherein at least part of the alkalizing agent is added to the cellulose starting material before the etherification and/or crosslinking reactions take place to obtain alkalized cellulose; the crosslinking agent and the etherifying agent are added one after the other in random order or simultaneously; the crosslinking agent is an alkali metal thmetaphosphate; and the crosslinking and etherification steps are performed at an elevated temperature. Additionally, the invention relates to crosslinked cellulose ethers obtainable by the above process having a viscosity and/or water absorption capacity higher than their non-crosslinked equivalents and the use thereof.

摘要： A process is disclosed for producing biosorbents by phosphorylation of cellulose-containing materials with phosphoric acid or ammonium phosphate in the presence of urea. Also disclosed are biosorbents with particular good use properties. Biosorbents of this type are used, in particular, for removing heavy metals from aqueous solutions. Proceeding from the disadvantages of the known prior art, purification costs of resultant raw products should be lowered and the formation of unwanted soluble organic polymer phosphates as by-products should be prevented. The biosorbents should have an improved mechanical strength and very good use properties. The disclosed biosorbents contain 5-10 % phosphorus and 1-4 % nitrogen in the form of carbamide groups. The synthesis mixture is mixed with elementary sulphur before starting the reaction in order to produce biosorbents with an increased mechanical strength. The proposed procedure allows reducing the otherwise customary reaction temperatures by about 40° C.
