Title (EN) LUBRICANT COMPOSITIONS COMPRISING ETHYLENE PROPYLENE COPOLYMERS AND METHODS FOR MAKING THEM
(FR) COMPOSITIONS LUBRIFIANTES COMPRENANT DES COPOLYMÈRES D'ÉTHYLÈNE ET DE PROPYLÈNE ET PROCÉDÉS DE FABRICATION ASSOCIÉS
Abstract:
(EN) Lubricant compositions, as well as processes for their formulation, are provided. The lubricant compositions comprise an oil basestock and one or more blocky ethylene propylene copolymers. The copolymers are preferably prepared using metallocene catalyst systems but without using a chain shuttling agent.
(FR) La présente invention concerne des compositions lubrifiantes ainsi que des procédés pour leur préparation. Les compositions lubrifiantes comprennent une huile de base et un ou plusieurs copolymères d'éthylène et de propylène séquencés. Les copolymères sont de préférence préparés à l'aide de systèmes catalytiques à base de métallocènes mais sans utiliser d'agent d'échange réversible de chaînes.
