Polymer combination useful in fuel oil to improve cold flow properties

Patent ·
OSTI ID:5202420
Ethylene polymers or copolymers, which are pour depressants for middle distillate fuel, in combination with a second polymer having alkyl groups of 6 to 18 carbon atoms, and derived from either dicarboxylic acid esters or olefins, are useful in improving the cold flow properties of middle distillate fuel oils wherein a portion, e.g., 5 wt. % or more, of the fuel boils above 700/sup 0/F. 7 tables.
