Abstract: An abrasive material (abradant) based on finely divided abrasive particles bonded to one another and/or to a support by means of a binder, where the binder is the solid component of an aqueous polymer dispersion obtainable by polymerising unsaturated monomers which can be polymerised by means of free radicals, in the aqueous phase in the presence of a monosaccharide, oligosaccharide or polysaccharide, oxidatively, hydrolytically and/or enzymatically degraded polysaccharides, chemically modified mono-, oligo- and polysaccharides, or mixtures of said compounds, by the process of free-radical aqueous emulsion polymerisation.

Abstract: Storage-stable aq. polymer dispersions are claimed, which are obtd. by dispersing a mixt. of: (a) 15-50 (wt.) copolymer (A) of 1.5-15% 3-10C comonomer (I) contg. a carboxylic acid or anhydride gp., 30-98.5% 1-20C alkyl (meth)acrylate (II), 0-60% vinyl-aromatics (III), 0-20% copolymerisable carbonyl cpds. (IV) and 0-20% other organic comonomers (V) and (b) 50-85% copolymer (B) of 40-100% (II) and 0-60% (III), (IV) and/or (V), in water, with addn. of NH3 and a polyhydrazide (C). (A) and (B) together contain up to 65% units of (II), which forms a homopolymer with Tg below 0 deg.C and (A) and/or (B) contains (IV) units. The claims also cover the prodn. of the dispersions. A soln. of a mixt. of (A) and (B) in an organic solvent is prepd. by prepg. one copolymer in the soln. obtd. by polymerisation of the other, then the mixt. is dispersed in water, with addn. of NH3, excess solvent is distilled off if necessary and then (C) is added, pref. in an amt. of 0.1-1 equiv. (C)/equiv. carbonyl gps. in the (A+B) mixt.

Abstract: The invention relates to products of a reaction of condensation products based on substituted ureas with di- and/or polycarboxylic acid derivatives, their preparation and their use. These reaction products each contain at least two cyclic urea units and can be prepared either by reacting primary diamines or polyamines with ureas and subsequently reacting the products with predominantly C-H-acidic aldehydes or by reacting primary amines with isocyanates, subsequently reacting the products with predominantly C-H-acidic aldehydes in the presence of acidic catalysts and subsequently reacting the products with di- and/or polycarboxylic acid derivatives. These products are suitable for the preparation of heat-curable coating compositions and for the preparation of binders for cathodic electrodeposition coating.

Abstract: Products of the condensation of sulphonated phenols, urea, further organic nitrogen bases and formaldehyde, obtainable by (A) sulphonation of phenols using from 1.0 to 1.5 mol of sulphuric acid per mole of phenol and (B) condensation of these sulphonation products with (a) from 0.5 to 1.8 mol of urea per mole of phenol, (b) from 0.001 to 0.5 mol of at least one further organic nitrogen base per mole of phenol, and (c) from 1.0 to 3.0 mol of formaldehyde per mole of phenol. The condensation products are suitable as tanning agents in the production of leather and pelts and as spray assistants for redispersible polymer powders.
