An aqueous composition comprises a mixture of

Polymer composition for use as aqueous floor adhesive

Flooring adhesives based on styrene-butadiene copolymers

The invention relates to a method of producing seals and coatings, and of bonding tiles and floor coverings, in which aqueous dispersions containing at least 20% by weight of filler and comprising a polymer mixture of a) an acrylate polymer A having a K value of from 5 to 55 and a glass transition temperature of below &minus;10&deg; C. and b) an acrylate copolymer having a glass transition temperature of from &minus;50 to &plus;50&deg; C., are applied as sealants, coating materials or single-side adhesives. The compositions which are used, based on the filler-containing dispersions of the polymer mixture, are notable in processing for improved fixing in the wet and dry state, high heat stability, good adhesion to rubber and, since they are essentially free from organic solvents, plasticizers and resins, by a high level of environment-friendliness.

Production of seals and coating and the bonding of tiles or floor coverings

An aqueous composition is essentially free of organic solvents, plasticizers and additional tackifiers and contains water and 20-99% by weight of a polymer and 1-80% by weight of a filler, the percentages by weight being based on the sum of the components of the aqueous composition, with the exception of water.

Flooring adhesives

Pulverulent adhesives comprise a redispersible polymer powder based on a polymer which can be obtained in the presence of a protective colloid, and additionally comprise a filler, an alkaline additive and, if desired, an emulsifier and other additives.

Pulverulent adhesive

Aqueous dispersions which contain a synthetic polymer obtained by free radical polymerization and a rosin are prepared by a process in which an aqueous dispersion of the synthetic polymer obtained by free radical polymerization is mixed with an aqueous formulation of a rosin which contains from 0.1 to 0.5 mol, based on 100 g of rosin, of carboxyl groups.

Solvent-free adhesive composition based on an aqueous acrylate latex

Tiles are laid using a tile adhesive which is based on a polymer dispersion and conventional additives and contains, as a thickener, a compound of the general formula I ##STR1## where R is a radical of dihydric to hexahydric alcohol of 2 to 10 carbon atoms, which radical is bonded via oxygen, R.sup.1 is alkyl, alkoxymethyl or alkenyloxymethyl or a mixture of these radicals, each having 16 to 30 carbon atoms in the alkyl, alkoxy or alkenyloxy radical, A is --CH.sub.2 CH.sub.2 --O-- (=EO) alone or as a mixture with ##STR2## --CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 --O--, where A is not less than 50, preferably not less than 70, mol % of --CH.sub.2 CH.sub.2 O--, x is from 12 to 500, y has a mean value (averaged over a large number of molecules) of from 0.3 to 5, preferably from 0.5 to 2, and n is an integer from 2 to 6.

Water-soluble terpolymers and their preparation

In the manufacture of flocked textiles by applying a polymer emulsion, flocking and drying, a heat-sensitized polymer emulsion is used and the emulsion coat is first only gelled, by heating, in the zone adjoining the textile substrate, and is then flocked and dried at an elevated temperature.
