(EN) The invention relates to the field involved in the production of aqueous compositions comprising rheology modifying agents, in particular the production of aqueous detergent or cosmetic compositions having improved, thickening and clarity properties, as well as good suspension properties. In particular, the invention relates to a rheology modifying agent which is a copolymer obtained by means of polymerisation of at least one crosslinking monomer with at least one anionic monomer comprising at least one polymerisable ethylenic unsaturation and at least one hydrophobic non-ionic monomer comprising at least one polymerisable ethylenic unsaturation.

Copolymer having thickening and suspension properties

A cross-linkable composition with controlled cross-linking as a material is used for fixing and thermally insulating tubes used for casing in drill holes, especially oil drill holes, during exploitation operations, such as oil extraction, in the drill hole. The cross-linkable composition includes at least one diene polyol, at least one polyisocyanate, and at least one heat insulating liquid filler.

Use of a fluid composition with delayed cross-linking for holding a casing inside a drill hole and method for reinforcing a drill hole
