Abstract: 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.

Abstract: Preparing an aqueous polymer dispersion comprises supplying at least one portion of ethylenically unsaturated monomers, a portion of water, at least one portion of polymer synthesized from ethylenically unsaturated monocarboxylic and/or dicarboxylic acid, ethylenically unsaturated compound(s) and further monomers, and at least portions of auxiliaries to a polymerization vessel together, without an emulsion being formed through a feed line. Preparing an aqueous polymer dispersion including dispersed polymer particles of addition polymer A1 obtainable by semi-continuous free-radical emulsion polymerization of ethylenically unsaturated monomers in the presence of an addition polymer A2 comprises supplying portion(s) of the ethylenically unsaturated monomers, a portion of water, portion(s) of the polymer A2 and, if desired, at least portions of further auxiliaries to the polymerization vessel together, without an emulsion being formed through a feed line. The addition polymer A2 is synthesized from 50-99.5 wt.% ethylenically unsaturated monocarboxylic and/or dicarboxylic acid, 0.5-50 wt.% ethylenically unsaturated compound(s) and up to 20 wt.% further monomer(s). The ethylenically unsaturated compound is ester of ethylenically unsaturated monocarboxylic acid or monoester and diester of ethylenically unsaturated dicarboxylic acid with an amine containing hydroxyl group(s).

Abstract: Thermally curable binding agents based on an aqueous polymer dispersion, containing an emulsion polymer (EP), a polymer which consists of at least 5 wt. % ethylenically unsaturated monocarboxylic acid, dicarboxylic acid or dicarboxylic acid anhydride (acid polymer SP) and monofunctional or multifunctional epoxy compounds as curing agents. The monofunctional or multifunctional epoxy compound is, preferably, introduced into the aqueous polymer dispersion in a liquid state. The thermally curable binding agent ca n contain a polymol or an alkanolamine, in addition to the epoxy compound, as curing agents.

Abstract: The use of an aqueous dispersion paint (A) with a pigment content of 40-200 wt.% (based on polymer component) is claimed for coating buildings or parts of buildings, where the polymer component comprises an emulsion copolymer, 0.5-30 wt.% of which is derived from polyoxyalkylene (meth)acrylate monomers (I). (A) include novel paints (A'), containing other specific monomers in addition to (I). The use of an aqueous dispersion paint (A) with a pigment content of 40-200 wt. % (based on polymer component) is claimed for coating buildings or parts of buildings, where the polymer component comprises an emulsion copolymer, 0.5-30 wt.% of which is derived from monomers of formula (I). R1 = H or Me; X = divalent polyoxyalkylene group having 1-50 oxyalkylene units; and R2 = H or 1-20C aliphatic or aromatic hydrocarbyl (preferably 1-4C alkyl). An Independent claim is included for a novel aqueous dispersion paint (A') comprising a pigment and an emulsion copolymer, where the pigment content is 40-200 wt.% based on the copolymer content, the copolymer has a glass transition temperature below 30 degrees C and the copolymer comprises (wt.%) (1) 1-8C alkyl (meth)acrylates and/or vinyl aromatic compounds (40-99.5) (2) monomer (I) (0.5-30); and (3) further monomers (0-50).
