  • Patent number: 6407170
    Abstract: A dispersant is prepared from an amine and a hydrocarbyl-substituted acylating agent, wherein the hydrocarbyl substituent is a polymerized olefin having a polydispersity {overscore (M)}w/{overscore (M)}n of greater than 5. Such polyolefin substituents are prepared by polymerization of olefins in the presence of a calcined catalyst comprising a partially or fully neutralized ammonium salt of a heteropolyacid.
