The invention relates to fiber-containing pasty construction materials, containing a) one or more fillers, b) optionally additives, characterized in that they contain c) fibers, d) one or more polymers based on one or more ethylenically unsaturated monomers, having a glass transition temperature Tg of &#x2267;&#x2212;15&#xb0; C., e) &#x2266;5% by weight hydraulically setting binders and f) water, wherein the information in % by weight relates to the dry weight of the fiber-containing pasty construction materials. The invention also relates to a process for producing a reinforcing composition free of woven reinforcing fabrics.

Fiber-containing pasty construction materials

The invention describes amphiphilic polymer compounds which are prepared by

Amphiphilic polymer compounds, method for the production thereof and their use

A description is given of azetidine derivatives and methods for producing them, and of their use as a latent curing component for resins having functional groups which are reactive toward amino groups. The particular advantages of the curing component proposed in accordance with the invention, such as effective producibility, high environmental friendliness, and excellent storage stability of the resin/curing agent mixtures, make these azetidine derivatives outstandingly suitable for one-component, moisture-hardening polymer compositions, which are of special interest in particular for the production of (floor) coatings, sealants, and adhesives.

A description is given of an optionally fluorinated polyurethane-polymer hybrid dispersion with enhanced surface properties (low critical surface tensions &#x3b3;and very high contact angles &#x3b8;) which is obtainable by The polyurethane-polymer hybrid dispersion of the invention can be prepared in solvent-free or low-solvent fashion and with high solids content and requires only a very low level of stabilizing groups.

Polyurethane-polymer hybrid-dispersion with enhanced surface properties, method for the production and utilization thereof

A method for producing self-emulsifiable, aqueous polyurethane resins by a) preparing a premix of polyol component including a least one diol having a molar mass of 500 to 5,000 Dalton, at least one polyhydroxyalkane at least one anionically modifiable dihydroxyalkane-carboxylic acid and 0 to 9 parts by weight of a solvent component in desired ratios; b) reacting a polyisocyanate component the premix from stage a) to give a polyurethane preadduct, c) reacting the polyurethane preadduct from stage b) with either the premix from stage a) or with an anionically modifiable dihydroxyalkanecarboxylic acid to give a polyurethane prepolymer; d) mixing the polyurethane prepolymer from stage c) with a prepared mixture of water, a neutralizing component and an antifoam component; and thereafter or simultaneously reacting the aqueous polyurethane prepolymer from stage d) with a chain-extending component which is diluted with water.

Solvent-free polyrethane-polymer-hybrid-dispersion and use thereof

Hybrid polyurethane-polymer dispersion with high film hardness, method for the production and the use thereof

A self-crosslinking polyurethane polymer hybrid dispersion based on oxidatively drying polyols having a high degree of film hardness is described, which is characterized in that it contains the reaction components claimed. The advantages of the polyurethane polymer hybrid dispersion according to the invention, such as a high degree of hardness in combination with high flexibility of the tear-free films, good resistance to chemicals, high stability of the dispersions in a wide pH range, good stability in the freezing and thawing cycle and the use of economical raw materials, are achieved in a simplified synthesis pathway wityout subsequent chemical crosslinking, and simultaneously with a low content of organic solvent (&lE;4% by weight) and good film formation at temperatures of &gE;&plus;10&deg; C.
