(FR) ADDITIFS POLYMERES
Abstract
(EN)
An additive comprising an oil-soluble polymer of number average molecular weight in the range of 200 to 50,000, the polymer having or including a polymer backbone carrying a plurality of the same or different functional groups that give rise to cetane improving properties in a fuel oil when the polymer is an additive therefor.
(FR)
Additif comprenant un polymère soluble dans l'huile d'un poids moléculaire moyen pouvant aller de 200 à 50 000, le polymère comprenant ou comportant un squelette de polymère portant plusieurs groupes fonctionnels identiques ou différents conférant une meilleure aptitude à l'allumage à un carburant contenant le polymère comme additif.
