|---|---|---|
| 20120330002 | HETEROGENEOUS THIOL-ENE CLICK MODIFICATIONS OF SOLID POLYSACCHARIDE-BASED MATERIALS - This invention concerns the first environmentally benign heterogeneous modification of polysaccharide-based material in native solid state by thiol-ene “click chemistry”. The direct reaction of a thiol with an un-activated double or triple bond by thiol-ene and thiol-enyne click modification is thermally or photochemically catalyzed and is completely metal-free and allows for a highly modular approach to modifications of fibers and fiber-based materials. | 12-27-2012 |
| 20110114276 | SHEET-FORMED FIBROUS MATERIAL WITH IMPROVED STRENGTH PROPERTY - A method of improving a strength property of a sheet-formed fibrous material formed from an aqueous slurry of cellulose fiber, including coating at least one face of the material with a coating formulation including a polysaccharide containing at least two carboxylic groups and low molecular weight organic mono-, di- or poly-carboxylic acid in an aqueous carrier, keeping the coated face at a temperature of 50° C. or more for a time sufficient to obtain the desired improvement including drying of the material. | 05-19-2011 |
| 20090111980 | MODIFICATION OF AMINES AND ALCOHOLS - A process for the modification of amines and alcohols, comprising (i) providing a substrate having amino groups or alcohol groups, wherein said substrate is, e.g., a polysaccharide; (ii) providing a modifying agent which is a lactone, an ester, a polyester, a carbonate, a polycarbonate, a lactide, a glycolide, an anhydride, an acid, a thioester or a carbamate; (iii) providing a catalyst which is, e.g., a amino acid or an organic acid; and (iv) reacting the substrate with the modifying agent in the presence of the catalyst. | 04-30-2009 |
