Abstract:
The present invention provides a composition comprising a) at least 1 % by weight of copolymer synthesized from monomers M comprising i) at least one ethylenically unsaturated monomer M1 containing sulfonic acid groups, ii) at least one monomer M2 selected from C 1 -C 4 alkyl (meth)acrylates, and iii) at least one monomer M3 selected from C 6 -C 22 alkyl (meth)acrylates; b) at least 10% by weight of organic solvent; c) not more than 10% by weight of water; d) at least 1 % by weight of water-insoluble pesticide; and e) at least 1 % by weight of nonionic surfactant. Further provided is a process for preparing this composition by contacting the copolymer, the organic solvent, the water-insoluble pesticide, and the nonionic surfactant. The invention relates additionally to the agrochemical application of the composition.
Abstract:
The present invention relates to a use of a copolymer comprising N-vinyllactam, and vinylimidazol or a quaternized vinylimidazol in polymerized form as dispersing agent in an aqueous composition containing a water-insoluble pesticide. Further on, it relates to an aqueous composition which contains a copolymer comprising in polymerized form at least 20 mol % N-vinyllactam, and at least 1 mol % vinylimidazol or a quaternized vinylimidazol, a water-insoluble pesticide, and a dissolved salt. The invention also relates to a method for preparing the said composition by mixing water, the water-insoluble pesticide, the salt and the copolymer. Another subject is a method for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired attack by insects or mites and/or for regulating the growth of plants, where said composition is allowed to act on the particular pests, their habitat or the plants to be protected from the particular pest, the soil and/or on undesired plants and/or the useful plants and/or their habitat.
Abstract:
The invention relates to an anhydrous formulation comprising: a) a first pesticide in a dissolved form, b) a second pesticide in the form of suspended particles, c) an alkyl lactate, and d) an alcohol. The invention also relates to a method for controlling phytopathogenic fungi and/or unwanted plant growth and/or unwanted insect or acaride infestations, and/or for regulating the growth of plants. Said formulation is left to act on the respective pests, on the habitat thereof, or on the plants to be protected from the respective pests, on the ground and/or on unwanted plants and/or the useful plants and/or the habitat thereof. The invention also relates to the use of the formulation for increasing the resistance to rain of the applied pesticides.
Abstract:
The present invention relates to the use of certain homo- or copolymers P for stabilizing organic active ingredients in aqueous compositions and/or formulations which comprise surface-active substances.
Abstract:
A process for preparing copolymers in solid form, wherein the copolymers are obtained by free-radically initiated polymerization of a mixture of 30 to 80% by weight of N-vinyllactam, 10 to 50% by weight of vinyl acetate and 10 to 50% by weight of a polyether, in the presence of at least one solvent, with the proviso that the sum of i), ii) and iii) is 100% by weight, characterized in that the solvents are removed from the polymerization mixture with the aid of an extruder.
Abstract:
The invention relates to the application of polyvinyl lactam-polyvinyl acetate block copolymers as solubilizers for agents which are minimally soluble in water.
Abstract:
The utilization of copolymers obtained by means of radically initiated copolymerization of a) 80 to 99,5% vinyl acetate by weight and b) 0,5 to 20% by weight of a sulfonate group-carrying, mono-olefinically unsaturated monomer, as solubilizers for substances with low solubility in water.
