Title (EN) LUBRICATING OIL COMPOSITION AND PROCESS FOR PRODUCING SAME
(FR) COMPOSITION D"HUILE DE LUBRIFICATION ET SON PROCEDE DE FABRICATION
Abstract: front page image
(EN)A lubricating oil composition composed of an oil-soluble graft copolymer, prepared by grafting a small amount of graft monomer selected from the group consisting of unsaturated monocarboxylic acid saturated esters, saturated carboxylic acid unsaturated esters, and unsaturated epoxy compounds to a copolymer having substantially no carbon-to-carbon double bonds expressed in terms of iodine value, having substantially no oxygen-containing functional groups, and having a number-average molecular weight of about 5,000 - about 100,000, selected from the group consisting of hydrogenation products of copolymers of (Alpha)-olefins containing 2 -20 carbon atoms, copolymers between styrene and (Alpha)-olefin containing 2 -20 carbon atoms, and copolymers between styrene and diolefin; and a process for producing same.
(FR)Une composition d"huile de lubrification composee d"un copolymere greffe soluble dans l"huile, preparee par greffage d"une petite quantite d"un monomere de greffe choisi parmi le groupe comprenant des esters satures d"acides monocarboxyliques non satures, d"esters non sature s d"acides carboxyliques satures, et de composes epoxy non satures sur un copolymere n"ayant pratiquement aucune liaison double carbone-carbone exprimee en terme de valeur iode, n"ayant pas de groupe fonctionnel contenant de l"oxygene et ayant un poids moleculaire moyen d"environ 5000 a 100000 choisis parmi le groupe de produits d"hydrogenation de copolymeres d"(Alpha)-olefines contenant entre 2 et 20 atomes de carbone, des copolymeres de styrene et d"(Alpha)-olefine contenant de 2 a 20 atomes de carbone, et des copolymeres de styrene et de diolefines; et un procede pour sa production.
