Abstract: The invention relates to modified cationic polymers which can be obtained by reacting (a) water-soluble, polymeric compounds containing NH groups with (b ) compounds which are at least bifunctional with regard to NH groups, which contain at least one alkyl radical or alkenyl radical having at least 8 C atoms, and which contain, as a functional group, a halohydrin, epoxide, carboxyl, chloroformate or isocyanate group or a halogen atom. The invention also relates to a method for producing the polymers by reacting the compound s of groups (a) and (b), and to the use of the modified cationic polymers duri ng the production of paper as fixing agents for papermaking stock containing interfering substances.

Abstract: Described is the use of terminal group capped fatty acid amide alkoxylates of the formula (I): R1-CO-NH-(CH2)n-O-(AO)x-R2 in which R1 is a C5-C21 alkyl or akenyl group, R2 is a C1-C4 alkyl group, A is C2-C4 alkylene, n is 2 or 3 and x is a number from 1 to 6, as non ionic surfactants or emulsifiers in washing, cleaning or bodycare agents, as surface-active substances for applications in the electroplating field, in the photographic industry, in the transport of crude oil, in the pharmaceutical industry, in plant nutrition and in plantprotection formulations, as well as surface-active substances for use in the manufacture of emulsions, pigments and synthetic-polymer dispersions.
