Hydrocarbyl substituted carboxylic acylating agents are made by reacting, optionally in the presence of chlorine or bromine, (A) one or more alpha-beta olefinically unsaturated carboxylic acid reagents containing 2 to about 20 carbon atoms, exclusive of the carboxyl-based groups with (B) one or more high molecular weight olefin polymers of more than 30 carbon atoms selected from the group consisting of (i) polymers of C12-C30 mono-olefins, and (ii) chlorinated or brominated analogs of (i). This invention includes the acylated amine and/or alcohol derivatives of these hydrocarbyl-substituted carboxylic acid acylating agents, and the use of such derivatives and agents in lubricants and normally liquid fuels.
