    摘要： The invention relates to the use of a copolymer comprising, in a polymerized form: (a) 80 to 99.9 mole percent of at least one monomer A containing one respective heterocycle which is provided with at least one N atom and is composed of 3 to 10 ring members and a C2-C6 alkenyl group that is bound to a C ring atom or N ring atom of the heterocycle; and (b) 0.1 to 20 mole percent of at least one monomer B which is polymerizable with monomer A and contains a monoethylenically unsaturated double bond and a linear or branched poIy-C2-C4 alkylene oxide group with an average of 4 to 500C2-C4 alkylene oxide units in liquid and solid detergent formulations, the percentages being in relation to the total amount of monomers polymerized for producing the copolymer. The invention further relates to a method for producing such a copolymer and a liquid or solid detergent formulation comprising at least one such copolymer.

    摘要： The invention relates to sulfonic acid group-containing copolymers, which also contain the following constituents that are incorporated by polymerization in a statistical or block-by-block manner: (a) 30 to 95 mol % of a least one monoethylenically unsaturated carboxylic acid, one monoethylenically unsaturated carboxylic acid ester, or one water-soluble salt of a monoethylenically unsaturated carboxylic acid; (b) 3 to 35 mol % of at least one sulfonic acid group-containing monomer of formula (I), in which the variables have the following meanings: R represents hydrogen or methyl; X represents a chemical bond or -C00-R -; R represents unbranched or branched C1-C4 alkylene; M represents hydrogen, alkali metal or ammonium, and; (c) 2 to 35 mol % of at least one non-ionic monomer of formula (II), in which the variables have the following meanings: R represents hydrogen or methyl; R represents a chemical bond or unbranched or branched C1-C6 alkylene; R represents identical or different unbranched or branched C2-C4 alkylene groups; R represents unbranched or branched C1-C6 alkyl, C5-C8 cycloalkyl or aryl, and; n represents 3 to 50. These copolymers are used as an additive in detergents and cleansers.

    摘要： The invention relates to the use of free aromatic acids comprising at least two aromatic ring systems, or at least two acid functionalities, and/or the salts thereof, for influencing stone formations when mining underground petroleum and/or natural gas deposits. The free acids are used in particular when influencing and primarily controlling the inflow of acid in stone formations in a so-called acidizing process. Suitable salts of the indicated aromatic acids serve for reducing the stone permeability and in particular for reducing water inflow. The invention further relates to corresponding methods in addition to said use.

    摘要： The invention relates to the use of a mixture containing a surfactant and a cosurfactant in the form of an aqueous solution for flooding underground hydrocarbon fields in order to mobilise and extract hydrocarbons therefrom, wherein the cosurfactant is embodied in the form of a substance or the group of substances selected from an amphiphilic comb polymer comprising a backbone which is provided with two or more side chains which differ from each other and/or from the backbone in terms of the amphiphilic character thereof, the amphiphilic polymer comprises one or several hydrophobic sub-groups [A2] based on a polyisobutene block, wherein at least 50 Mol % of polyisobutene macromolecules have terminal double bonds and one or several hydrophobic sub-groups [A2] or an amphiphilic polymer of a general structural formula (I).

    摘要： A process of forming a second aqueous suspension of solid particles (15) by gravity sedimentation of a first aqueous suspension of solid particles (14) in a vessel (13), comprising the steps of, adding at least one organic polymeric flocculant (12) to the first aqueous suspension of solid particles (14) thereby forming a suspension of flocculated solids (1 1 ), which flocculated solids settle to form a bed of consolidated solids (5), introduction of an effective amount of an agent, into the i) bed of consolidated solids (5) or ii) the flocculated solids that are settling (1 1 ), in order to form the second aqueous suspension (15), in which the second aqueous suspension of solid particles (15) is of higher solids content than the first aqueous suspension of solid particles (14), and in which the agent is selected from the group consisting of free radical agents and oxidising agents, wherein the agent is introduced means selected from the group consisting of A) one or more rakes (10) which convey the agent; B) one or more conduits (16) entering through the top of the vessel through which the agent is introduced C) one or more apertures or conduits (17) in the side walls of the vessel through which the agent is introduced; D) one or more apertures or conduits (18) in the base of the vessel through which the agent is introduced; E) introducing the agent through one or more apertures or conduits (19) in the feed line conveying the bed of consolidated solids from the base of the vessel, preferably between the base of the vessel and a pump; and F) one or more sparges (20) through which the agent is introduced.
