The invention relates to a pelletized organopolysiloxane material, to a process for producing the pelletized material, and to the use of the pelletized organopolysiloxane material as an additive for thermoplastics.

Pelletized organopolysiloxane material

The invention relates to a method for stabilizing the gas flow in water-bearing natural gas deposits or reservoirs which produce at least 50 l of water per 1000 m,(Vn) of extracted natural gas. According to the method, a dispersion comprising the following components is injected into the water-bearing rock: A) an organosilicon compound as the dispersed phase; B) a hydrophilic dispersion agent, which can be mixed with water, and, if needed, C) a dispersing additive.

Method for stabilizing the gas flow in water-bearing natural gas deposits or reservoirs

The invention relates to aqueous emulsions containing (A) organo-hydrogenated polysiloxanes optionally mixed with organopolysiloxanes free of Si linked hydrogen and organyloxy groups, (B) organopolysiloxanes containing organyloxy groups as stabilizers, (C) emulsifiers and (D) water.

The organopolysiloxane particles consist of a single molecule, are crosslinked and have an average diameter of 5 to 200 nm. At least 80% of the particles have a diameter which deviates from the average diameter by not more than 30%. The particles are soluble in a solvent to the extent of at least 5% by weight.

Monodisperse soluble organopolysiloxane particles

An epoxy resin molding material comprising an epoxy resin, a phenolic resin and a powder flexibilizer which has a core-shell structure composed of a solid silicone core and an organic polymer shell is a reliable epoxy resin molding material for sealing electronic parts which is excellent in, for example, thermal shock resistance and reflow soldering resistance, and is free from the troublesome deterioration in, for example, the appearance and marking properties of molded products, and to provide a semiconductor sealed by the molding material.

Epoxy resin molding for sealing electronic parts containing organic

The invention relates to the preparation of organopolysiloxane microemulsions, wherein the components (A) organopolysiloxane, (B) emulsifier, (C) water, optionally, (D) cosurfactant and optionally (E) acid are brought together and mixed in any desired sequence. Microemulsions are formed spontaneously without introduction of energy in the form of heat or severe shearing forces.
