Abstract
According to the present invention, novel oil soluble compositions useful as dispersants are provided by reaction of a mono- or polycarboxylic acid acylating reactant with at least one heterocyclic polyol of the formula: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are the same or different and are selected from the group consisting of H, alkyl and --CH(OH)R.sup.5, wherein R.sup.5 is C.sub.1 to C.sub.10 alkyl, and wherein X and Y are the same or different and are H or C.sub.1 to C.sub.10 alkyl, with the proviso that at least one of R.sup.1, R.sub.2, R.sub.3 and R.sup.4 is the --CH(OH)R.sup.5 moiety.
