Abstract

See full text

The present invention relates to a thickener preparable by a process which comprises obtaining a cationic polymer by inverse emulsion polymerization of

    a) at least one water-soluble ethylenically unsaturated monomer comprising at least one cationic monomer, optionally at least one anionic monomer and/or optionally at least one nonionic monomer,b) at least one ethylenically unsaturated associative monomer,c) optionally at least one crosslinker,d) optionally at least one chain transfer agent,the temperature being kept constant during the inverse emulsion polymerization and being at least 40° C., preferably 50 to 90° C., and after the inverse emulsion polymerization has ended, activator being added to obtain the thickener.
