    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an aqueous solution of a copolymer, wherein the time of occupation of a reactor for producing an aqueous solution of a copolymer can be shortened by avoiding or reducing foaming. SOLUTION: In producing an aqueous solution of a copolymer comprising (a) 50-99.5 mass% of at least one ethylenically unsaturated monocarboxylic acid and/or dicarboxylic acid (monomer A), (b) 0.5-50 mass% of at least one ethylenically unsaturated compound (monomer B) selected from an ester of an amine having at least one hydroxy group with an ethylenically unsaturated monocarboxylic acid, and a monoester and diester of the amine with an ethylenically unsaturated dicarboxylic acid, and (c) up to 20 mass% of at least one other monomer (monomer C), the monomers A, B and C are polymerized in an aqueous medium in the presence of at least one foam inhibitor.

    Abstract: The invention relates to the use of formaldehyde-free aqueous binders with broad molecular weight distribution for substrates, comprising (A) 0 to 100 wt. % of an ethylenically-unsaturated acid anhydride, or an ethylenically-unsaturated carboxylic acid the carboxylic acid group of which can form an anhydride or mixtures thereof, (B) 100 to 0 wt. % of an ethylenically-unsaturated compound, (C) at least one polyfunctional curing agent or mixtures thereof and (D) 1 - 80 wt. % of an aqueous polymer dispersion, whereby the polymers from A) and B), obtained by radical polymerisation, on classification in a coordinate system of mean molecular weights Mw and polydispersity values, lie on the surface above a straight line, defined by the linear equation y = 1,25x + 20,000 and displaced in the y-direction by at least + 3,000, whereby the x-axis is the weight average molecular weight and the y axis is the polydispersity value multiplied by 10,000. The invention further relates to the binder itself and the use thereof for example, for moulded bodies, mats or sheets, in particular, for fibrous and particulate substrates such as fibre fleece, glass fibres, rockwool, reprocessed cotton, natural fibres or artificial fibres.

    Abstract: The use of polyacrylic acid (I) with an average mol. wt. (M w) of 5000-30000 and with end groups containing sulfur and at least 2 carbon atoms, which is at least partly neutralised with alkali metal hydroxide or ammonia, as auxiliary material for the wet-milling of calcium carbonate. Independent claims are also included for finely-divided suspensions of CaCO 3 containing 0.1-2 wt% (I), obtained by wet-milling in presence of (I).

    Abstract: An ethylenically unsaturated monocarboxylic acid and/or dicarboxylic acid (monomer A) (in wt.%) (50-99.5), an ethylenically unsaturated compound chosen from specific esters (0.5-50) (monomer B), and an optional monomer (monomer C) (up to 20) are polymerized in aqueous medium in the presence of foam inhibitor(s), to prepare an aqueous copolymer solution. An ethylenically unsaturated monocarboxylic acid and/or dicarboxylic acid (monomer A) (in wt.%) (50-99.5), ethylenically unsaturated compound (0.5-50) (monomer B), and an optional monomer (monomer C) (up to 20), are polymerized in an aqueous medium in the presence of at least one foam inhibitor, to prepare an aqueous copolymer solution. The monomer (B) is chosen from esters of ethylenically unsaturated monocarboxylic acids and monoesters and diesters of ethylenically unsaturated dicarboxylic acids with an amine containing at least one hydroxyl group.
