Abstract: front page image
(EN)Copolymers of unsaturated fatty esters capable of being obtained by copolymerization in a mineral oil of a percentage a) of an ester of a carboxylic acid A¿1?, of a percentage b) of an ester of a carboxylic acid A¿2? and a percentage c) of an ester of a carboxylic acid A¿3?, wherein a), is between 12 and 20 %, c) is between 14 and 30% and b), which is preferably 72 and 45 %, is such that a)+b)+c)= 100 %. The copolymers in accordance with the invention are remployed as viscosity improver in lubricating oils.
(FR)Copolymères d'esters gras insaturés pouvant être obtenus par copolymérisation dans une huile minérale d'un certain pourcentage a) d'un ester d'un acide carboxylique A¿1?, d'un certain pourcentage b) d'un ester d'acide carboxylique A¿2? et d'un certain pourcentage c) d'un ester d'un acide carboxylique A¿3?, dans lesquels a) se situe entre 12 et 20 %, c) entre 14 et 30 % et b) de préférence entre 72 et 45 %, de sorte que a)+b)+c) = 100 %. Ces copolymères sont employés comme adjuvants de viscosité dans des huiles lubrifiantes.
