Abstract

PURPOSE: The titled additive modifying wax crystals in a fuel oil and improving fluidity thereof at a low temp. which comprises an unsaturated discarboxylate ester adduct with ethylene-vinyl carboxylate copolymer and, if necessary, a specified compd.
CONSTITUTION: A fluidity-modifying additive comprising (A) an unsaturated dicarboxylate ester adduct with ethylene-vinyl carboxylate copolymer of number- average MW≥500, contg. 2W30mol% vinyl carboxylate unit and, if necessary, (B) a compd. selected from an ethylene-vinyl acetate copolymer, ethylene-acrylate copolymer, polyalkylene halide, alkyl(meth)-acrylate polymer, condensate of chlorinated paraffin and naphthalene, nitrogen-contg. deriv. of alkenylsuccinic acid, etc. Fluidity of a fuel oil is modified by the addition of 0.001W0.1wt% said additive.
