  • Liquid hydrocarbon compositions of improved behavior in the cold and containing diene polymers
    Patent number: 4021207
    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.
    Type: Grant
    Filed: November 27, 1974
    Date of Patent: May 3, 1977
    Assignee: Institut Francais du Petrole, et l'Entreprise de Recherches et d'Activities Petolieres-Elf
