Abstract:
The present invention relates to a thickener comprising at least one cationic polymer and at least one activator. The at least one cationic polymer is preparable by 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, and d) optionally at least one chain transfer agent. The ratio of activator to cationic polymer is >10 to 100 [% by weight/% by weight].
Abstract:
The present invention relates to hydrophobically modified cationic polymers obtainable by the polymerization of one or more cationic ethylenically unsaturated monomers with an ethylenically unsaturated monomer having anhydride, imide, lactone, carboxylic acid, isocyanate or blocked isocyanate group and a reactive siloxane and processes for preparing them. These polymers are useful i.a. as a depositioning aid of hydrophobic actives onto fibrous substrates.

Abstract:
The present invention relates to a thickener preparable by a process wherein a polymer is obtained by an inverse emulsion polymerization ofa) at least one water-soluble ethylenically unsaturated monomer comprising at least one anionic monomer and/or 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,where the temperature during the inverse emulsion polymerization is kept constant and is at least 40° C., preferably 50 to 90° C., and, when the inverse emulsion polymerization is complete, the activator is added, giving the thickener.
