摘要
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.
