The invention relates to a condensation product obtainable by reaction of

Condensation products based on bicyclic or polycyclic aromatics or heteroaromatics

The invention relates to a method for stabilizing and securing banks, hillsides and slopes, and structures present at least partly in moving waters, such as supporting and construction elements, by composite materials comprising mineral particles, preferably stones, in particular crushed rock, and an epoxy resin.

Method for stabilising and securing rivers, slopes and embankments

The invention relates to aqueous pigment preparations containing i) at least one copolymer P of ethylenically unsaturated monomers M in the form of an aqueous polymer dispersion which contains between 0.1 and 1.5 weight %, in relation to the total weight of the copolymer P, of polymerized itaconic acid as acid monomer M1, its salts and/or anhydride, where up to 50 weight % of the itaconic acid can be substituted by another monomer having at least one acid group or a neutralized acid group, and whose glass transition temperature T lies between &minus;10 and &plus;50&deg; C.; ii) at least one inorganic pigment; iii) possibly inorganic fillers; and iv) standard additives. The invention also relates to the use of the copolymers P containing itaconic acid for improving the wet-abrasion resistance of polymer-bound coatings containing pigments.

Dispersion resins containing itaconic acid for improving wet abrasion resistance

Use of naphthalenesulfonic acid-formaldehyde condensates products as drying aids

The use is described of polysulfide-free preparations comprising, based on solids content, from 40 to 99.5% by weight of at least one water-dispersible copolymer and from 0.5 to 10% by weight of at least one alkoxylated ionic or nonionic emulsifier, as additives for construction materials based on loam or clay. The building materials based on loam or clay and comprising the preparation are described, as are the use of the construction materials and a process for treating construction materials with the preparation.

A process for preparing an addition-polymer powder suitable for modifying a binding mineral building material by drying an aqueous addition-polymer dispersion whose film has a glass transition temperature Tg&lE;30&deg; C. and to which a drying assistant has been added comprises adding to the aqueous addition-polymer dispersion before drying only a drying assistant which will have a plasticizing or deplasticizing effect in the ready-to-use mix of the binding mineral building material with water and admixing the resulting dry addition-polymer powder with at least one assistant in the form of a finely divided solid which will have an opposite effect to the drying assistant added before drying.

Preparation of addition-polymer powder

A process for preparing aqueous polymer dispersions comprises first of all subjecting ethylenically unsaturated monomers to free-radical aqueous emulsion polymerization to prepare an aqueous dispersion of a polymer 1 having a glass transition temperature Tg , then dissolving further, comparatively hard monomers in the dispersed particles of the polymer 1, and subsequently carrying out free-radical polymerization of said monomers dissolved in said particles.
