| description | In some embodiments, the present disclosure provides for ethylene- C3 to C20 alpha- olefins random copolymers having an ethylene content of about 45 wt% to about 70 wt% and a Mw(DRI)/Mn(DRI) of from 1.1 to 1.9. In some embodiments, the ethylene-propylene random copolymer is used as a viscosity modifier in a lubricating composition.
Dans certains modes de réalisation, la présente invention concerne des copolymères aléatoires d'éthylène et d'alpha-oléfines en C3 à C20 présentant une teneur en éthylène d'environ 45 % en poids à environ 70 % en poids et un rapport Mw(DRI)/Mn(DRI) de 1,1 à 1,9. Dans certains modes de réalisation, le copolymère aléatoire d'éthylène et de propylène est utilisé comme modificateur de viscosité dans une composition lubrifiante. |
