| description | The present disclosure also relates to lubrication compositions comprising a long branched ethylene copolymer and methods for making compositions. Compositions of the present disclosure can be a composition including an oil and a ethylene copolymer, the copolymer having one or more of an MWD from about 2.0 to about 6.5; an Mw(LS) from about 30,000 to about 300,000 g/mol; a g′vis of from about 0.5 to about 0.97; an ethylene content of about 40 wt % to less than 80 wt %. The compostion has a shear stability index (30 cycles) of from about 1% to about 60%; and a kinematic viscosity at 100° C. of from about 3 cSt to about 25 cSt. A method of making a composition includes blending an oil with a copolymer is also disclosed. Additionally, provided are novel long chain branched ethylene propylene copolymers and methods to produce such copolymers. |
