Patent

CA 2732278

The present invention relates to a copolymer comprising units derived from monomers (i) an .alpha.-olefin and (ii) an ethylenically unsaturated carboxylic acid or derivatives thereof esterified with a primary alcohol branched at the .beta.- or higher position, wherein the copolymer has a reduced specific viscosity of up to 0.08. The invention further provides for a lubricating composition containing said copolymer. The invention further provides a method and use of controlling viscosity index by supplying to an oil of lubricating viscosity the copolymer with pendant groups. In addition, the copolymer of the present invention may be useful as a base oil replacement.

L'invention concerne un copolymère contenant des unités dérivées de monomère, comprenant (i) une a-oléfine et (ii) un acide carboxylique éthyléniquement insaturé, ou des dérivés de celui-ci estérifiés avec un alcool primaire ramifié au niveau de la position ß ou supérieure, le copolymère ayant une viscosité spécifique réduite allant jusqu'à 0,08. L'invention fournit en outre une composition lubrifiante contenant le copolymère. L'invention fournit en outre un procédé et une utilisation de commande d'index de viscosité en dotant une huile lubrifiante de la viscosité du copolymère avec des groupes pendants. De plus, le copolymère de la présente invention peut être utile en tant que remplacement d'huile de base.
