An acrylic acid polymer having a weight average molecular weight Min the range from 3500 to 2000 g/mol and a polydispersity index M/M&#x2264;2.5, wherein 30% to 60% of the acid groups of the acrylic acid polymers have been neutralized with calcium ions, 30% to 70% of the acrylic acid polymers have been neutralized with sodium ions and 0% to 10% of the acid groups of the acrylic acid polymers have not been neutralized.

Acrylic acid polymers neutralized with sodium and calcium ions and having a narrow molecular weight distribution

Process for treating subterranean oil-bearing formations comprising carbonate rocks with an aqueous composition comprising cationic ammonium salts comprising four hydrocarbon radicals wherein at least one of the hydrocarbon radicals is substituted by an OH-group. The process may be a process for enhanced oil recovery, fracturing, acidizing or antiscale treatment.

Process for treating subterranean oil-bearing formations comprising carbonate rocks

The present invention relates to a liquid composition comprising A) an organic active ingredient which is sparingly water-soluble and sparingly oil-soluble, in dissolved form, B) an oil which is soluble in water at 20&#xb0; C. to at most 20 g/l, and C) an ionic liquid comprising a cation and an anion as described below. Also provided is a process for the preparation of the liquid composition, where the active ingredient, the oil and the ionic liquid are brought into contact; and also the use of the ionic liquid for increasing the solubility of the active ingredient in an oil.

Composition comprising active ingredient, oil and ionic liquid

Method of fracturing subterranean formations using aqueous compositions comprising at least an aqueous base fluid, proppants, a viscosifier, at least one flowback aid and removing at least a portion of the aqueous fracturing fluid from the formation after fracturing. The flowback aid is selected from the group of alkyl or alkenyl polyglucosides, carboxylated alkyl or alkenyl polyglucosides and alkoxylated branched alcohols.

Method of fracturing a subterranean formation with use flowback aids

Process for water-wetting oil-wet surfaces by applying an aqueous formulation comprising at least one wettability modifier which is a water-soluble ester of an alkoxylated saccharide to the oil-wet surface. The oil-wet surfaces may be any hydrophobic surfaces such as the rocks of subterranean oil-bearing formations.

Process for water wetting oil-wet surfaces

The present invention provides a composition comprising a pesticide and a copolymer, which contains in polymerized form acrylic acid and/or methacrylic acid (monomer A); a mono C-Calkyl terminated poly(C6 alkylene glycol)(meth)acrylate (monomer B); and a C-Calkyl(meth)acrylate (monomer C). Further on, it provides a process for preparing said composition by contacting the pesticide and the copolymer; a method for controlling phytopathogenic fungi and/or unwanted plant growth and/or unwanted insect or mite infestation and/or for regulating the growth of plants, wherein said composition is caused to act on the respective pests, their habitat or the plants to be protected from the respective pest, to the soil and/or to unwanted plants and/or the crop plants and/or their habitat; and a plant propagation material comprising said composition.

Agroformulation comprising copolymer of acrylic acid, poly(alkylene glycol) (meth)acrylate, and alkyl (meth)acrylate

A process for mineral oil production, in which an aqueous formulation comprising tris(2-hydroxyphenyl)methane of the general formula (I) is injected into a mineral oil deposit through an injection well and the crude oil is withdrawn from the deposit through a production well,  

Use of tris(2-hydroxyphenyl)methane derivatives for tertiary mineral oil production

New types of derivatives of tris(2-hydroxyphenyl)methanes which have, as functional groups, polyalkoxy groups or polyalkoxy groups modified with terminal hydrophilic groups, preparation of such compounds and their use, especially as surfactants and thickeners.
