Abstract
A succinimide dispersant, which is the reaction product of hydrocarbons or polymers functionalized by halogenation (e.g. chlorination), thermal 'ene' reaction or free radical grafting and derivatized with a heavy polyamine. A heavy polyamine is a mixture of polyalkylenepolyamines comprising small amounts of lower polyamine oligomers such as tetraethylene pentamine and pentahexamine but primarily oligomers with 7 or more nitrogens, 2 or more primary amines per molecule, and more extensive branching than conventional polyamine mixtures.
