ABSTRACT:
An oil-soluble dispersant containing sulfolane groups therein. The dispersant is made by reacting at least one polycarboxylic acid acylating agent having at least one polyalkene substituent of high or low molecular weight with a (B) polyamine and a (C) sulfolene. Desirably, the polyamine is branched or contains amino side chains and thus contains a plurality of primary amines. The acylating agents are characterized by the presence within their structure of at least 0.5 acylating groups for each equivalent weight of the polyalkene substituent. The compositions are useful in various motor oils, marine oils, automatic transmission fluids and the like.
