The present invention relates to a composition comprising more than 25 weight % (based on the weight of the composition) of one or more ethylene polymers having an Mw of 20,000 g / mole or more and at least 0.1 weight % of a liquid hydrocarbon modifier where the modifier has:1) a viscosity index of 120 or more, and2) an kinematic viscosity of 3 to 3000 cSt at 100° C., and3) a pour point of −10° C. or less, and4) a flash point of 200° C. or more;and wherein the modifier contains less than 5 weight % of functional groups selected from hydroxide, aryls, substituted aryls, halogens, alkoxys, carboxylates, esters, acrylates, oxygen, nitrogen, and carboxyl, based upon the weight of the modifier.
