Abstract: 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 an 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 composition 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.

Abstract: The present disclosure relates to lubricant compositions comprising a branched copolymer and methods for making such compositions. Lubricant compositions of the present disclosure comprise an oil and a copolymer and have a high temperature high shear (HTHS) viscosity of about 5 or less, shear stability index (30 cycles) of from about 2% to about 80%, a ratio of thickening efficiency to shear stability index (30 cycles) of from about 1 :2 to about 1 :30, a kinematic viscosity at 100°C of from about 3 cSt to about 30 cSt, and a thickening efficiency of about 1 or more. In another class of embodiments, the present disclosure provides a lubricant composition comprising a first and a second copolymers wherein the first copolymer has an ethylene content higher than that of the second copolymer, and wherein at least one of the two copolymers is a long chain branched ethylene copolymer.
