    摘要: A graft copolymer based on a component a) consisting of silica which has been reacted with an unsaturated silane, and a polymer component b) containing sulphonic acid is proposed. The silica used is preferably a nanosilica and the unsaturated silane is an ethylenically unsaturated alkoxysilane. The component b) is represented by a copolymer based on AMPS and a further ethylenically unsaturated monomer. The polymer according to the invention, which as a rule is a nanocomposite, is outstandingly suitable as an additive in construction chemistry applications and in the development, exploitation and completion of underground mineral oil and natural gas deposits, its effect as a water retention agent being particularly advantageous at high salinities and increased temperatures.

    摘要: Subject matter of the present invention is a drilling fluid additive based on sulfonated asphalt, which comprises a water soluble and anionic polymer component in quantities of 0.1 to 20 wt. %, with respect to the total additive in addition to the asphalt component. With this additive the water solubility of sulfonated asphalt can be markedly increased. This additive, whose polymer component is thermally highly stable, is utilized primarily in water- and/or oil-based drilling fluids and in particular in the exploration of subterraneous petroleum and natural gas deposits. Typical polymer components to consider are representatives of polycondensation products, such as phenol resins, ketone resins and sulfonated naphthalene, acetone and amino plasticizer resins (for example urea and melamine resins).

    摘要: This process for the preparation of homogeneous, low-viscous and long-term-stable polymer dispersion in mineral oils, in which a liquid mineral oil component, to which a water-soluble polymer and an organophilic bentonite have been added, is stirred, is distinguished by the fact that the dispersing process is carried out at speeds of ≧1000 rpm. The duration of the stirring operation should preferably be between 5 and 60 minutes, and both aromatized and/or dearomatized mineral oils and also as typical water-soluble polymers, which moreover may have a maximum water content of 25% by weight, can be used. By means of this relatively simple process, homogeneous polymer-containing mineral oil dispersions having a low viscosity and at the same time pronounced long-term stability, which are suitable in particular for use in oil and gas exploration, are obtained in very short mixing times.
