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, and 2) an kinematic viscosity of 3 to 3000 cSt at 100°C , and 3) a pour point of -10°C or less, and 4) 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.
