    摘要: The invention relates to a method for the production of at least alkylated, non-ionic cellulose ethers, whereby at least 10% of all hydroxy groups contained therein are alkylated and which may flocculate in water, within a temperature range of 45 to 95° C. The invention is characterized in that at least one surfactant in solid, liquid, or solution form is added to the cellulose for production of the cellulose ether.

    摘要: Process for the preparation of low molecular weight polysaccharide ethers which can be employed in binders for improving adhesive power and film-forming properties, by oxidative degradation of relatively high molecular weight polysaccharide ethers, which comprises initially introducing a relatively high molecular weight polysaccharide ether in suspension (e.g. in a slurry), adding a perborate or a mixture of perborate and perborate activator, and carrying out the oxidative degradation at a temperature of between 25.degree. and 90.degree. C.

    摘要: Water-soluble polysaccharides which contain a) substituents selected from the group consisting of alkyl, hydroxyalkyl, carboxyalkyl and sulfoalkyl, b) N,N-disubstituted aminoalkyl groups, are prepared by alkylation of a polysaccharide in the presence of a base with one or more alkylation reagents, selected from the group consisting of compounds transferring alkyl groups, compounds transferring hydroxyalkyl groups, compounds transferring carboxyalkyl groups and compounds transferring sulfoalkyl groups, and also with an N,N-disubstituted amino-alkylsulfuric acid ester. The modified polysaccharides are used in paper production and waste-water purification and also in cosmetics.
