The invention relates to polymer compositions containing inorganic or organic particles which either have been surface-treated before the production of the compositions or are dispersed by special polyether-modified siloxanes through the production of the compositions.

Surface treatment of particles and their use

Surface treatment of titanium dioxide, barium sulfate, zinc sulfide, and/or lithopone particles, and mixtures of said particles with specific alkoxylated siloxanes for the improvement of dispersion in plastics.

The invention describes amine-amide-functional siloxanes and a process for the preparation thereof by the chemical reaction of SiOH-functional siloxanes with amino-functional silanes in the presence of carboxylic acid anhydrides.

Process for the preparation of amine-amide-functional siloxanes

The invention relates to the defoaming of ionic liquids and also to compositions comprising at least one ionic liquid and at least one antifoam and, if appropriate, a solvent and/or further auxiliaries or additives.

Defoaming of ionic liquids

Water repellents based on reactive siloxanes with polyfunctional silylalkoxy modification of the siloxane backbone and processes for hydrophobizing mineral fiber components.

Hydrophobizing construction elements comprising mineral fibers

The invention relates to a process for the preparation of branched siloxanes containing R&#x2014;SiOunits, where R=organic radical, wherein straight-chain polysiloxanes containing silane hydrogen in the polymer chain are reacted in the presence of ammonium or metal carboxylates as a catalyst in the absence of hydroxy-functional organic compounds, and to siloxanes thus prepared and the use thereof in the preparation of polyurethane foams and antifoam formulations.

Process for the preparation of branched polyorganosiloxanes

The object of the present invention is to provide antifoams which have a good antifoam effect in aqueous dispersions of polymeric organic substances, cause no wetting defects when these dispersions are applied to a surface and at the same time retain their antifoam activity even after prolonged storage at temperatures down to the freezing point.

Use of grafted polyethersiloxane copolymers for improving the low-temperature stability of antifoams in aqueous dispersions
