Patent

CA 2348538

A lubricating oil composition comprising a di-block copolymer of poly(monovinyl aromatic hydrocarbon) and hydrogenated poly(conjugated diene) as a dispersant additive is described. The said di- block copolymer preferably comprises poly(monovinyl aromatic hydrocarbon) in the molecular weight range 8,000 - 30,000. The diblock copolymers are useful as dispersant additives in lubricant oils, reduce heavy metal corrosion, reduce degradation of elastomeric seals and are less sensitive to the presence of over-based detergents.

L'invention concerne une composition d'huile lubrifiante qui contient comme additif dispersant un copolymère biséquencé constitué de poly(hydrocarbure monovinylique aromatique) et de poly(diène conjugué) hydrogéné. Dans ledit copolymère, le poly(hydrocarbure monovinylique aromatique) a de préférence un poids moléculaire compris entre 8000 et 30000. Ces copolymères biséquencés sont utiles comme dispersants dans les huiles lubrifiantes, réduisent la corrosion par les métaux lourds et la dégradation des joints élastomères, et sont moins sensibles à la présence de détergents hyperbasiques.
