The invention relates to a process for producing polymer composites suitable for absorbing and storing aqueous liquids, to the polymer composites obtainable by this process, and to the use of the polymer composites. The process comprises free-radical polymerization of a monomer composition M comprising 50 to 100% by weight, based on the total amount of monomers A and B, of at least one monomer A having one ethylenic double bond and at least one neutralizable acid group, 0 to 50% by weight of optionally one or more comonomers B which are different than the monomers A and have one ethylenic double bond, and 1 to 10% by weight, based on the total amount of monomers A and B, of at least one crosslinker C.

Process for producing high-swellability polymer composites

The present invention relates to soil-applied CR granules obtainable by applying an active-ingredient-comprising coating to a solid carrier in a fluidized bed, to a process for the preparation of these soil-applied granules, and to a method for controlling phytopathogenic fungi, undesired vegetation, undesired attack by insects and/or for regulating the growth of plants using the soil-applied CR granules according to the invention.

Soil granulates with controlled active ingredient release (cr soil granulates)

A description is given of a polymer dispersion comprising i) polymer particles dispersed in an aqueous medium and composed of units of ethylenically unsaturated monomers, ii) a water-soluble polymeric polyelectrolyte which along a polymeric backbone carries a large number of ionic groups of uniform charge character or groups which can be ionized to such groups, and iii) an ionic surfactant which carries an ionic group having a charge character opposite to that of the polymeric polyelectrolyte, or a group which can be ionized to such a group. The polymer dispersion can be coagulated by simple dilution with water.

Polymer dispersions

An aqueous polymer dispersion, a process for preparing it, and substrates bound on the basis of it are described.

Thermohardening polymer dispersion

The invention relates to a thermally hardenable polymer dispersion powder and the use of said powder as a binding agent in particular for fibrous and grainy materials. The binding agent in powder form is obtained by drying a polymer dispersion which comprises a carboxyl-group-containing polymerization component in addition to, optionally, a hydroxy-alkylated amine.

The invention relates to a method for producing shell catalysts for the catalytic vapor-phase oxidation of aromatic carboxylic acids and/or carboxylic acid anhydrides comprised of a supporting core and of catalytically active metal oxides which are deposited in a shell-shaped manner on said supporting core. The inventive catalysts are obtained by spraying an aqueous active mass suspension, said suspension containing the active metal oxides, at higher temperatures onto the hot supporting material which has a temperature ranging from 50 to 450&deg; C. The aqueous active mass suspension contains 1 to 10 wt. %, with regard to the solid content of the active mass suspension, a binding agent comprised of A) a polymerizate obtained by radical polymerization, containing 5 to 100 wt. % of monomers (a) in the form of ethylenically unsaturated acid anhydrides or ethylenically unsaturated dicarboxylic acids whose carboxyl groups can form an anhydride and containing 0 to 95 wt. % monoethylenically unsaturated monomers (b) with the provision that the monomers (a) and (b) comprise, on average, a maximum of 6 carbon atoms which are not functionalized with groups containing oxygen, and of B) an alkanolamine having at least 2 OH groups, a maximum of 2 nitrogen atoms and a maximum of 8 C-atoms, whereby the weight ratio A:B ranges from 1:0.05 to 1:1.

Heat-curable aqueous compositions which comprise a carboxyl-containing polymer component and optionally a hydroxyalkylated amine are used as binders for shaped articles.

Thermosetting aqueous compositions

Described is a polymer dispersion comprising in an aqueous medium (a) dispersed particles of a polymer containing more than from 5 to 20% by weight of &agr;,&bgr;-ethylenically unsaturated mono- or dicarboxylic acid, (b) a dissolved polymer containing from 60 to 100% by weight of &agr;,&bgr;-ethylenically unsaturated mono- or dicarboxylic acid, and (c) an alkoxylated long-chain amine. Heat-curable compositions are obtained by adding polyfunctional alcohols and, optionally, reaction accelerant. The polymer dispersions and the heat-curable compositions are suitable for use as binders for textile sheetlike structures and for moldings.
