摘要:
The present invention relates to new comb polymers, to a method for the production thereof, and to the use thereof for stabilizing water-insoluble or hardly soluble active or effective ingredients in an aqueous phase. The invention further relates to the use of the comb polymers in the production of active ingredient formulations or active ingredient preparations of water-insoluble active or effective ingredients, especially for agents for plant protection. The comb polymers can be obtained by copolymerization of monoethylenically unsaturated monomers M, wherein the monomers M comprise: a) at least one monoethylenically unsaturated monomer Ma, selected from esters of monoethylenically unsaturated C3-C8-monocarboxylic acids having C1-C20-alkanols, C5-C10-cycloalkanols, phenyl-C1-C4-alkanols or phenoxy-C1-C4-alkanols and the diesters of monoethylenically unsaturated C4-C8-dicarboxylic acids having C1-C20-alkanols, C5-C10-cycloalkanols, phenyl-C1-C4-alkanols or phenoxy-C1-C4-alkanols; and b) at least one monoethylenically unsaturated monomer Mb, selected from the esters of monoethylenically unsaturated C3-C8-monocarboxylic acids and the monoesters and diesters of monoethylenically unsaturated C4-C8-dicarboxylic acids having poly-(C2-C4-alkylene ether)ols, and wherein the total sum of the monomers Ma and Mb amounts at least to 60 wt.% of the monomers M constituting the comb polymer.

(1) A perfluoroalkyl diester of maleic acid or fumaric acid, (2) a copolymer obtained by polymerizing the perfluoroalkyl ester, a lower alkyl (meth)acrylate and, if necessary, styrene, and (3) a stainproofing agent comprising the copolymer give excellent water repellency, oil repellency and stainproof properties which have never been heretofore obtained.
摘要:
The invention comprises a thickening agent comprising an aqueous-soluble polymerization product of one or more water-soluble monomers which are sufficiently water-soluble to form at least a 10 weight percent solution when dissolved in water and which undergo addition polymerization to form polymers which are water-soluble; and at least one second monomer of the formula: wherein R is a hydrocarbyl radical which contributes hydrophobic character to the second monomer, Z is a divalent linking group, M is a divalent hydrocarbyl or substituted hydrocarbyl radical and Y is an ionic species which contributes hydrophilic character to the molecule. These compositions are useful for thickening aqueous mediums, in particular, for thickening equeous media containing water-soluble electrolytes. Such thickened aqueous media retain their viscosity when subjected to shear, heat or high electrolyte concentrations. The thickened aqueous solutions may be used in enhanced oil recovery processes as fluid mobility control agents, fracturing fluids and drilling muds, as well as hydraulic fluids and lubricants.

The present invention provides a laminate comprising a void-containing layer and a pressure-sensitive adhesive/adhesive layer. In the laminate of the present invention, a pressure-sensitive adhesive or an adhesive is less likely penetrated into voids in the void-containing layer. The void-containing layer includes nanoparticles, surfaces of which are modified with a compound having a surface orientation, wherein the void-containing layer has a void fraction of 35 vol% or more. The pressure-sensitive adhesive/adhesive layer is laminated on the void/containing layer through a layer formed of the nanoparticles. The peak pore diameter of the void-containing layer is 50 nm or less, and the volume average particle diameter of the nanoparticles is 50 nm or less.

摘要:
Hair is treated with a copolymer of an unsaturated ester and a styrene sulphonate monomer to reducing damage to hair caused by subsequent heat treatment. The styrene sulphonate monomer is desirably sodium styrene sulphonate and the unsaturated ester is desirably of an unsaturated monocarboxylic acid, such as (meth)acrylic acid, or dicarboxylic acid, such as maleic acid, and an alcohol, desirably an alkoxylated alcohol such as ethoxylated lanolin alcohol. Formulations for hair treatment generally include from about 0.5 to about 25% by weight of the copolymer.
