摘要:
The present invention relates to the use of specific amphiphilic copolymers as synergistic adjuvant for agrotechnical applications. Suitable agrotechnical compositions are also described. Thus, the addition of such copolymers makes possible an accelerated uptake of active ingredients by the plant. The copolymers or salts thereof to be used comprise monomer units (i) based on at least one olefin and/or at least one vinyl ether, (ii) based on at least one ethylenically unsaturated dicarboxylic acid and/or at least one ethylenically unsaturated dicarboxylic acid derivative, and, optionally (iii) based on at least one further copolymerizable comonomer.

Copolymers based on N-vinylamide as adjuvant and compositions for the agrotechnical field The present invention relates to specific copolymers based on N-vinylamide and to their use as activity-improving adjuvant in the agrotechnical field and in particular in the field of plant protection. Appropriate agrotechnical compositions are likewise described. The copolymers are copolymers of vinylamides and ethylenically unsaturated carboxylic acid esters which are alkoxylated.

The invention relates to the use of a cationic crosslinked polymer which is preparable by free-radical polymerization in the presence of salts and of protective colloids in cosmetics.
摘要:
A process for the production of water-soluble or water-swellable cationic polymers by (i) free-radically initiated copolymerization of monomer mixtures in water comprising (a) from 1 to 99% by weight of a cationic monomer or quaternizable monomer, (b) from 1 to 99% by weight of a water-soluble monomer, (c) from 0 to 10% by weight of a bi- or polyfunctional, free-radically copolymerizable monomer, adjusting the amounts (a) to (c) in such a way that the resulting polymer has an overall positive charge, in the presence of 1 to 100% of the amount of a salt which is necessary to saturate the reaction medium with said salt and in the presence of 0.1 to 20% by weight referred to the weight of the dispersion, of an amphoteric dispersant having an overall negative charge, and (ii) subsequent quaternization of the polymer if the monomer (a) employed is a non-quaternized monomer is disclosed.

摘要:
A mixture comprising a surfactant and a cosurfactant is proposed wherein the cosurfactant used is an amphiphilic comb polymer having a backbone with two or more side chains attached to the backbone, where the side chains differ from one another and/or the side chains differ from the backbone in their amphiphilic character.
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.
