The invention relates to the use of mixtures of polymers comprising amine groups and polymers comprising amide groups for modifying the rheology of compositions comprising water, and to rheology modifying methods. In particular, the invention relates to the use of these mixtures for the thickening of compositions comprising water for cosmetic, human and animal nutrition, dermatology, pharmacy and detergents and cleaners, crop protection, surface modification and during petroleum production, such as, for example, enhanced oil recovery.
摘要:
The present invention relates to an aqueous polymer dispersion which is obtainable by free-radical polymerization of a monomer mixture which comprises at least one amide-group-containing compound, at least one crosslinker and at least one monomer with at least one cationogenic and/or cationic group. The invention further relates to the polymers obtainable by drying such a polymer dispersion, and to cosmetic or pharmaceutical compositions which comprise such a polymer dispersion or such a polymer.
