Abstract
Terpolymers of ethylene, vinyl acetate and isobutylene as flow improvers in distillate fuels. The terpolymers have number average molecular weights in the range of about 1,600 to about 3,000, and weight average molecular weights in the range of about 4,000 to about 18,000. These terpolymers provide improved low temperature flow characteristics in middle distillate fuels.
