  • Water-soluble, sulfoalkyl-containing, hydrophobically modified cellulose ethers, processes for preparing them, and their use in emulsion paints
    Patent number: 6313287
    Abstract: Water-soluble sulfoalkyl-containing hydrophobically modified cellulose ethers, processes for preparing them, and their use in emulsion paints The present invention relates to water-soluble ionic cellulose ethers from the group of the hydroxyalkylcelluloses which are substituted by on average from 0.001 to 1.0 alkyl group per anhydroglucose unit and which carry from 0.01 to 0.1 sulfoalkyl group per anhydroglucose unit, to processes for preparing them and to the use of water-soluble ionic cellulose ethers from the group of the hydroxyalkylcelluloses which are substituted by on average from 0.001 to 1.0 alkyl group per anhydroglucose unit and which carry from 0.01 to 0.4 sulfoalkyl group per anhydroglucose unit in emulsion paints.

  • Hydrophobically modified cellulose ethers, their preparation and use
    Publication number: 20010021387
    Abstract: The present invention relates to water-soluble, organosilylated cellulose ethers in which the organosilyl groups are attached hydrolysis-stably to the cellulose ethers and the remaining substituents on the silicon atoms of the organosilyl groups are likewise stable to hydrolysis. The cellulose ethers of the invention exhibit a strongly thickening action in aqueous solution, even at very low degrees of silylation, and are suitable as thickeners, for example, in paints, adhesives, and cosmetics. They are further suitable as protective colloids in the preparation of polymer dispersions.

  • Use of oxime ether derivatives for bioregulation in plants
    Patent number: 5364834
    Abstract: Oxime ether derivatives of the general formula IR.sup.1 R.sup.2 C.dbd.NO--CH.sub.2 --COOR.sup.3 Iwhere R.sup.1 and R.sup.2 independently of one another are each hydrogen or C.sub.1 -C.sub.6 -alkyl or, together with the carbon atom to which they are bonded, are C.sub.5 - or C.sub.6 -cycloalkyl and R.sup.3 is hydrogen or C.sub.1 -C.sub.6 -alkyl, are used for bioregulation in plants.
