Thermoviscosifying polymers, their synthesis and their uses in particular in the oil industry.

摘要

The invention relates to polymers the viscosity of which increases in solution, or significantly stabilizes with temperature. These polymers contain a hydrosoluble skeleton incorporating segments or carrying side chains which have a low solubility temperature ("LCST" property (Lower Critical Solution Temperature)). Uses in the chemical industry and the oil industry, in particular for oil or geothermal bore hole cementation, fracturing and industrial cleaning. <IMAGE>
