    Abstract: Cationic polymers for use in cosmetic formulations are obtained by polymerisation of quaternised nitrogen-containing monomers in presence of polyether-containing compounds in a reaction mixture with a water content of less than 20 wt%. Cationic polymers (CP) are used in cosmetic preparations, where CP are obtained by the polymerisation of (a) 3-30 wt% quaternary nitrogen-containing radically-polymerizable monomer(s) (a1) and/or direct precursor(s) thereof (a2) in the presence of (b) 70-97 wt% polyether-containing compound(s), (c) optionally 0-15 wt% other comonomers with a water solubility of more than 60 g/l at 25[deg]C and (d) optionally 0-15 wt% other comonomers with a water solubility of less than 60 g/l at 25[deg]C. The water content of the reaction mixture during polymerisation is less than 20 wt%, compounds (a2) (if used) are converted into compounds with quaternary N (a2') during or after polymerisation, and the mol ratio of (a1 + a2' + c) to monomers (d) is at least 2:1. Independent claims are also included for: (1) the inventive cationic polymers (CP); (2) a method as described above for the production of CP; and (3) cosmetic hair formulations containing (A) 0.05-20 wt% CP, 20-99.95 wt% water and/or alcohol and 0-79.05 wt% other components (OC), or (B) 0.1-10 wt% CP, 20-99.9 wt% water and/or alcohol, 0-70 wt% propellant and 0-20 wt% OC, or (C) 0.1-10 wt% CP, 55-94.8 wt% water and/or alcohol, 5-20 wt% propellant, 0.1-5 wt% emulsifier and 0-10 wt% OC, or (D) 0.1-10 wt% CP, 60-99.85 wt% water and/or alcohol, 0.05-10 wt% gel-former and 0-20 wt% OC, or (E) 0.05-10 wt% CP, 25-94.95 wt% water, 5-50 wt% surfactant, 0-5 wt% other conditioning agent and 0-10 wt% OC.

    Abstract: 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.
