Abstract (en)

[origin: DE102005019398A1] Preparation of precipitating polymers comprises spraying polymerization of a monomer solution containing at least an ethylenic unsaturated monomer, at least a solvent, optionally at least a cross-linker and optionally at least an initiator, where the monomer is soluble in the solvent and the obtained polymer through polymerization of the monomers, is insoluble in the solvent. An independent claim is included for a method for thickening aqueous fluids comprising using the polymer.
