Abstract: Process for tertiary mineral oil production in which an aqueous injection fluid comprising at least a water soluble polyacrylamide-(co)polymer dissolved in the aqueous fluid is injected into a mineral oil deposit and the aqueous injection fluid is prepared by mixing a liquid dispersion polymer composition comprising particles of polyacrylamide-(co)polymers dispersed in an organic, hydrophobic liquid with an aqueous fluid. Preferably, the process is carried out on an off-shore production site.

Abstract: Water-soluble, hydrophobically associating copolymers which comprise new types of hydrophobically associating monomers. The monomers comprise an ethylenically unsaturated group and a polyether group with block structure comprising a hydrophilic polyalkylene oxide block which consists essentially of ethylene oxide groups, and a terminal, hydrophobic polyalkylene oxide block which consists of alkylene oxides with at least 4, preferably at least 5 carbon atoms.

Abstract: A process for preparing salts of acrylamido-2-methylpropanesulfonic acid (A) using the steps of: preparing a solution of a contaminated salt of acrylamido-2-methyl-propanesulfonic acid (A) in an anhydrous organic solvent (L) using at least one basic component (B) selected from the group of alkali metal oxides, alkaline earth metal oxides, alkali metal hydroxides, alkaline earth metal hydroxides and amines of the formula (I) NRaRbRc  (I) where the Ra, Rb and Rc radicals are each independently: hydrogen, C1-C4-alkyl, hydroxy-C1-C4-alkyl or C1-C4-alkoxy, where the molar ratio of compound (A) to the basic component (B) is 1:1 to 1:3, recovering the dissolved salt of compound (A) by crystallization or by precipitation, by altering the temperature and/or the pressure and/or the concentration of the salt in the solution. This leads to salts which are low in by-products and are particularly suitable for polymerization.
