Abstract: This invention relates to an improvement in a water vapor absorbing and transmitting adhesive containing at least one organic binding agent which is insoluble in water, and an addition of at least one hydrophilic polymer, the improvement that the hydrophilic polymer is a swellable modified polymer in the form of small particles. The invention also relates to a process for the manufacture of the adhesive.

Abstract: PROCESS FOR THE PRODUCTION OF WATER-ADSORBING CELLULOSE ETHERS This invention relates to an improvement in the process for the production of water-adsorbing, but at least partially water-insoluble, cellulose ethers in which cellulose is alkalized in a liquid reaction medium and etherified in a manner such that by etherification only an at least largely water-soluble carboxymethyl cellulose, carboxymethyl hydroxyethyl cellulose, hydroxyethyl cellulose or methyl hydroxyethyl cellulose is produced, and in which the cellulose is reacted in an alkaline reaction medium before, during, or after the etherification with a crosslinking agent which is polyfunctional towards cellulose and selected from the group consisting of acrylamido methylene chloroacetamide, dichloroacetic acid, phosphorous oxychloride, or a compound in which at least two groups functional towards cellulose are the acrylamido group the chloroazomethine group or the allyloxy azomethlne group the improvement comprising effecting alkalization, etherification, and cross-linking in a liquid reaction medium other than isopropyl alcohol.

Abstract: Aqueous surfactant compositions containing a surfactant mixture of a) 55 to 85% by weight of an alkanesulphonate, petroleumsulphonate, olefinsulphonate or alkylbenzenesulphonate having a mean molecular weight of 280-400 and b) 15 to 45% by weight of an ether sulphonate of the formula RO(AO)mA'SO3M where R is C6-C20-alkyl or a phenyl group which is substituted by one to three alkyl groups having a total of 6 to 20 carbon atoms, A is a C2H4 or C3H6 group or a mixture of the two groups, A' is -C2H4- or -C3H6-, m is a number of 3 to 25, and M is an alkali metal atom or ammonium. These surfactant mixtures are suitable for tertiary oil recovery in combination with specific salt-stable copolymers based on polyarylamide. They form stable solutions or dispersions with highly saline water.
