| description | A cellulose ether having (i) one or more substituents selected from the group consisting of methyl, hydroxyethyl and hydroxypropyl, (ii) one or more hydrophobic substituents, and (iii) one or more cationic, tertiary amino, or anionic substituents, and having a retained dynamic viscosity, %?80/25, of at least 30 percent, wherein %? 80/25 = [dynamic solution viscosity at 80 °C / dynamic solution viscosity at 25°C] x 100, the dynamic solution viscosity at 25°C and 80° being measured as 1 % aqueous solution, is useful for modifying the viscosity of a composition selected from the group consisting of wellbore servicing fluids, cementitious formulations, ceramics, metal working fluids and cutting fluids.
L'invention porte sur un éther de cellulose qui possède (i) un ou plusieurs substituants choisis dans le groupe constitué par les substituants méthyle, hydroxyéthyle et hydroxypropyle, (ii) un ou plusieurs substituants hydrophobes et (iii) un ou plusieurs substituants cationiques, amino tertiaires ou anioniques, et dont la viscosité dynamique conservée, %?80/25, est d'au moins 30 pour cent, %?80/25 étant = [viscosité dynamique en solution à 80°C/viscosité dynamique en solution à 25°C] x 100, la viscosité dynamique en solution à 25°C et 80°C étant mesurée dans une solution aqueuse à 1 %. Ledit éther est utile pour la modification de la viscosité d'une composition choisie dans le groupe constitué par les fluides d'entretien de puits de forage, les formulations cimentaires, les céramiques, les fluides pour le travail des métaux et les fluides de coupe. |
