Abstract: Methyl vinyl ether is copolymerized with a comonomeric compound of the formula: CH2=CHOR wherein R is phenyl or alkyl of from three to 30 carbon atoms, to give a copolymer containing from 20 to 85 weight percent of said comonomeric compound and having an inherent viscosity (0.1 percent solution in toluene) at 25* C. in the range of 0.6 to 2.0. The resulting copolymer is soluble in hydrocarbon lubricating oils and exhibits a unique combination of properties, such as viscosity index improver, thickener, good shear stability, good 0* F. properties, and as ashless dispersant for gums, resins and other oxidation products, present or formed, in the lubricating oil during the operation of combustion engines of various types.
