A fuel additive having the formula: (see fig. I) wherein R1 and R2 are independently hydrogen or lower alkyl; R3 and R4 are independently hydrogen or lower alkyl and each R3 and R4 is independently selected in each -O-CHR3-CHR4- unit; R5 is hydrogen, alkyl having 1 to 100 carbon atoms, phenyl, aralkyl having 7 to 100 carbon atoms or alkaryl having 7 to 100 carbon atoms, or an acyl group of the formula: (see fig. II) where R6 is alkyl having 1 to 30 carbon atoms, phenyl, aralkyl having 7 to 36 carbon atoms or alkaryl having 7 to 36 carbon atoms; n is an integer from 5 to 100; and x is an integer from 0 to 10.

Additif d'essence de formula (voir la fig. I) où R1 et R2 sont, de façon indépendante, des hydrogènes ou des groupes alkyle à chaîne courte; R3 et R4 sont, de façon indépendante, des hydrogènes ou des groupes alkyle à chaîne courte et R3 et R4 sont choisis de façon indépendante dans chacune des unités -O-CHR3-CHR4-; R5 est un hydrogène ou l'un des groupes suivants : alkyle avec de 1 à 100 atomes de carbone, phényle, aralkyle avec de 7 à 100 atomes de carbone ou alkaryle avec 7 à 100 atomes de carbone ou group acyle de formula (voir la fig. II) où R6 est l'un des groupe suivants : alkyle avec de 1 à 30 atomes de carbone, phényle, aralkyle avec de 7 à 36 atomes de carbone ou alkaryle avec 7 à 36 atomes de carbone; n est un entier compris entre 5 et 100 et x est un entier compris entre 0 et 10.
