Substituted carboxylic acylating agents formed by reacting an olefin with a carboxylic reactant are further reacted with α-β unsaturated carboxylic compositions to form substituted carboxylic acylating agents. The substituted carboxylic acylating agents are further reacted with various compounds to form especially dispersants for use in oil compositions.
