Formaldehyde-free binders for shaped articles

Heat-curable aqueous compositions which comprise a carboxyl-containing polymer component and optionally a hydroxyalkylated amine are used as binders for shaped articles.

Thermosetting aqueous compositions

Thermally curable aqueous compositions comprising a low-acid and an acid-rich polymer component and also a hydroxyalkylated amine are used as binders for shaped articles.

Formaldehyde-free binder for mouldings

Cationically stabilized aqueous styrene/(meth)acrylate copolymer emulsions whose dispersed copolymer has a static glass transition temperature of from 40 to 110.degree. C. and which contain, as a dispersant, a mixture of at least one organic monoamine of .gtoreq.8 carbon atoms and an acid addition salt thereof are used as binders for moldings based on finely divided materials having a negative surface charge.

Use of cationically stabilized aqueous polymer emulsions as binders for

At least one compound ##STR1## is added to mineral building materials modified with polymers in order to increase their adhesive power on foams based on polystyrene.

Mineral building materials modified with polymers and containing at

Aqueous dispersions of polymers which have a high glass transition temperature and a low average molecular weight and contain a specific amount of methacrylic acid as polymerized units are suitable, in liquid or dried form, as additives for improving the flow behavior of cement-containing mineral building materials having binding properties.

Aqueous polymer dispersions

Aqueous polymer dispersions contain, as a dispersant, a mixture of an ethylene oxide/propylene oxide copolymer, an ethoxylated alkylphenol and/or an ethoxylated fatty alcohol, an ethoxylated polysaccharide and, if required, as a further component, sulfuric acid half-esterified with an ethoxylated alkylphenol and/or an ethoxylated fatty alcohol.

Polymer powders which are redispersible in water and are obtainable by atomizing aqueous polymer dispersions to which from 3 to 50% by weight, based on the polymer, of a water-soluble alkali metal salt or alkaline earth metal salt of a phenolsulfonic acid/formaldehyde condensate has been added are used as additives in hydraulic binders.

Polymer powders which are redispersible in water and can be prepared by
