Abstract: 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.

Abstract: A new binder for finely divided materials which does not emit formaldehyde on processing, is obtained from a composition which contains the reaction product of a di or tricarboxylic acid or its anhydride with ammonia and if necessary a primary amine and/or a compound having at least two OH groups, or as precursor of this reaction product, or a mixture of this di or tricarboxylic acid or its anhydride with a substance which releases ammonia on heating. The use of a composition containing: (i) at least one polycarboxylic acid of formula (I) with (ii) ammonia and if necessary (iii) primary amines and/or compounds with at least two OH groups, and/or a mixture of at least one polycarboxylic acid of formula I and/or its anhydride and at least one substance which releases ammonia on heating and if necessary primary amines and/or compounds with at least two OH groups. R = H or CH2COOH, X = OH or NH2 when Y =H, Y = OH or NH2 when X = H, or X and Y together = a pi -bond, and or an anhydride of polycarboxylic acid (I). Independent claims are included for: (1) a thermally hardenable substance containing at least one reaction product from (i) at least one polycarboxylic acid of formula (I), and R, X, Y, (ii), and (iii) are as defined above, and in addition, at least one further constituent selected from finely divided polymerisates of ethylenically unsaturated monomer , compounds with at least two OH groups, and polycarboxylic acid polymers; (2) a process for preparation of shaped bodies from finely divided materials, by impregnation or mixing of the finely divided material with the composition described above at 120 deg C; (3) a shaped body obtained as above; and (4) a flat-shaped article obtained as above.

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.
