Abstract
A process for preparing a copolymer of vinyl acetate and alkyl fumarate for use as an oil additive, characterized by reacting, in the presence of a suitable catalyst, monomers of alkyl fumarate and vinyl acetate in proportions of (1) 55% by mole of vinyl acetate units, (2) 7 to 35% by mole of lower alkyl fumarate units of 2 to 4 carbon atoms in the lower alkyl groups, (3) 34 to 45 mole% of units of average alkyl fumarate of 5 to 11 carbon atoms in the average alkyl groups and (4) 4 to 20 mol% of higher alkyl fumarate units of 12 to 18 carbon atoms in the higher alkyl groups, ascending the total of said units in said copolymer at 100 mol%.
