The present invention relates to oxazolidines derived from polyalkyl or polyalkenyl N-hydroxyalkyl succinimides, the obtainment process thereof, and their use to prevent and control the formation of deposits in internal combustion engines, primarily in formulations of additives to be applied to hydrocarbon fuels.
The oxazolidines derived from polyalkyl or polyalkenyl N-hydroxyalkyl succinimides of the present invention, have the structural formula
wherein:
R is a polyalkyl or polyalkenyl group having an average molecular weight ranging from 450 to 5000 daltons;
m is an integer between 1 and 5;
n is an integer between 0 and 1; and
R
