| Number | Title | Issue Date |
| 6534637 | Synthesis of chlorophenol red glucuronic acid This invention provides ଲ-D-Glucuronidase substrates of the formula: ##STR1## wherein R1, R2, and R7 -R12 are independently selected from the group consisting of: hydrogen, fluorine, chlorine, bromine, iodine, ... | 03/18/2003 |
| 6482876 | Agglomerates for the production of an aqueous binder system The invention relates to an agglomerate containing at least one of the following water-soluble or water-dispersible materials as a bonding base polymer: carboxylized and/or alkoxylized starch, cellulose ether and fully synthetic vinyl polymers and/or poly... | 11/19/2002 |
| 6392035 | Reactive cellulose and method for making same The invention concerns reactive cellulose, i.e. cellulose having in particular a very low degree of crystallinity obtainable with a high degree of purity. Said novel reactive cellulose is particularly used as raw material for making cellulose ethers. The ... | 05/21/2002 |
| 6372901 | Polysaccharides with alkyl-aryl hydrophobes and latex compositions containing same Polysaccharides, including hydroxyethyl cellulose, having alkyl-aryl hydrophobic substitution, provide latex compositions, such as paints, with improved rheology and stability. Improved processes for producing such polysaccharides are also provided.... | 04/16/2002 |
| 5612321 | Antioxidant grafted polysaccharides Grafted polysaccharide compositions comprising polysaccharides grafted with antioxidants on at least one hydroxyl group of the polysaccharide. The use of antioxidant grafted polysaccharides or antioxidant grafted crosslinked polysaccharides as a treatment... | 03/18/1997 |
| 5583214 | Dual functional cellulosic additives for latex compositions Cellulose ether derivatives comprising a hydrophobic substituent having an unsaturated alkyl portion are disclosed. The unsaturation in the alkyl portion of the hydrophobic substituent can promote crosslinking of the cellulose ether derivative. The cellul... | 12/10/1996 |
| 5426182 | Polysaccharides containing complex hydrophobic groups Polysaccharides, including hydroxyethyl cellulose, having complex hydrophobic group substitution, provide latex compositions, such as paints, with improved rheology and stability. Improved processes for producing such polysaccharides are also provided.... | 06/20/1995 |
| 5120838 | Alkylaryl hydrophobically modified cellulose ethers Cellulose ethers are disclosed which have sufficient nonionic substitution to render them water soluble and which are further modified with a C10 to C24 long chain alkylaryl group in an amount between 0.2% by weight and the amount wh... | 06/09/1992 |
| 5055570 | Cuprammonium-stable cellulose esters and carbamates for dialysis membranes A cellulose derivative comprising substitution-modified cellulose regenerated from a cuprammonium solution, the substituents being ester groups, wherein the acyl group represents one or more, optionally substituted, carbon chains with 10-36 carbon atoms, ... | 10/08/1991 |
| 5008385 | Cellulose derivatives and fibers and membranes made therefrom Cellulose derivatives are disclosed which have the following formula: ##STR1## wherein Z is selected from the group consisting of alkylene, alkenylene, alkynylene, cycloalkylene or benzylene or xylylene radicals, which may or may not be substituted; ... | 04/16/1991 |
| 4992538 | Silated polysaccharides Silated polysaccharides having 0.0005 to 2.0 silyl molar substitution per anhydrosaccharide unit form water resistant films when cast from aqueous solution and dried in the presence of atmospheric carbon dioxide. These films are soluble in aqueous caustic... | 02/12/1991 |
| 4582899 | Manufacturing method for cellulose ether having high degree of substitution A manufacturing method for cellulose ether having a high degree of substitution characterized in that an etherifying agent represented by a general formula RCH2 X (where R is aromatic group, heterocyclic group, vinyl group or ethynyl group or t... | 04/15/1986 |
| 4229572 | Purification of cellulose ether reaction product In the preparation of organosoluble cellulose ethers, the content of alkali metal (hydroxides and the salts thereof) in the resulting cellulose ether is reduced by forming a solution of the cellulose ether and an organic solvent, converting the alkali met... | 10/21/1980 |
