Abstract
The behavior in the cold of crude oil or petroleum distillates may be improved by incorporation of polymeric substances such as a hydrogenated polybutadiene or a hydrogenated copolymer of butadiene with at least one conjugated aliphatic diolefin of 5-8 carbon atoms. The additive is active at concentrations of from 10 to 1,000 grams per m.sup.3 of oil.
