Abstract: A stable liquid intermediate comprising a polyol, and/or an acid and/or a catalyst and/or water for the preparation of polymeric compositions, the polyol being polyester polyol, a polyoxpropylene-polyoxypropylene polyol or a mixture thereof. There is disclosed a method of use of said stable liquid intermediate wherein said stable liquid intermediate is mixed with rubber granules.

Abstract: The invention relates to an injection fixing arrangement (1) having an anchor sleeve (5) and an anchor rod (6), the anchor sleeve (5) having an anchoring region (9) with outlet apertures (10) for the outlet of mortar injected into the anchor sleeve (5), and the injection fixing arrangement (1) having a nut (7) as abutment for the article (2) being fixed. Injection fixing arrangements (1) of such a kind for proud-standing mounting are known. The invention proposes an injection fixing arrangement (1) for push-through mounting, wherein a transverse-force sleeve (11) follows the anchoring region (9) of the anchor sleeve (5).

Abstract: The invention relates to the use of aqueous, isocyanate-free, polyurethane dispersions with a solid content of ?30 wt. % and a solvent content of ?10 wt. % in sports floor coverings. The inventive polyurethane dispersions are particularly suitable for use as bonding agents for elastic coatings, spray coatings or flow coatings on elastic or rigid undersurfaces, adhesion promoters or primary coatings, fillers for sealing pores, adhesives for gluing pre-fabricated plastic coatings or for sealing sports floor coverings. The inventive polyurethane dispersions are environmentally friendly and easy to manufacture. They are also partly characterized by improved product features, e.g. mechanical properties, UV resistance and color stability, with respect to the corresponding sports floor coverings.

Abstract: A solvent-free polyurethane-polymer hybrid dispersion having a high solids content of polymer or formulation constituents is described, which is obtainable by a) the multistage preparation of a polyurethane base dispersion and b) by the subsequent preparation of a polyurethane-polymer hybrid dispersion. This polyurethane-polymer hybrid dispersion not only is distinguished by complete freedom from solvents and high solids contents in combination with low viscosity and a technically simple preparation process but also has excellent mechanical properties and, owing to the low hydrophilicity, high water resistance.

Abstract: The use of aqueous isocyanate-free polyurethane dispersions with a solids content of ≧30 wt. % and a solvent content of ≦10 wt. % in formulations for crack sealing coating systems is disclosed. Said use may be in a) primer, floating screed, floor coatings, spray coatings and/or sealants, on, preferably, primed building surfaces, b) roof coatings or paints and c) sealing of open-cast or subterranean mines. According to the invention, the disclosed polyurethane dispersions are not just more environmentally-friendly and easier to use, but also give a partly improved product property to the corresponding crack sealing coating systems, such as, for example, mechanical properties (tensile strength, stretching under tension, tear elongation), UV resistance and colour stability.
