  • Publication number: 20030105374
    Abstract: The present invention is related to a method for oligomerizing olefinic monomers under oligomerization conditions to form higher olefins. The novel method comprises contacting a feed comprising the olefinic monomers with a catalyst composition comprising the reaction product of: (a) a compound having a formula selected from the group consisting of M[S2C2(RaRb)]2 and M[S2C6(R1R2R3R4)]2, wherein M is a late transition metal, Ra, Rb, R1, R2, R3 and R4 are independently selected and may be the same or different and are selected from hydrogen, electron-withdrawing groups and unsubstituted and substituted hydrocarbyl groups; and (b) an activating cocatalyst. The improved method advantageously relates to oligomerizing olefinic monomers from feed streams having contaminants, especially sulfur-containing contaminants.

  • Patent number: 5871554
    Abstract: Novel polymers comprising polyolefin-substituted amines grafted with aromatic N-containing monomers such as aniline, have been found to provide oil soluble polymers having dispersant and antioxidant properties in oleaginous compositions, including fuel and lubricating oils. The polymers of this invention are further useful in electrical applications. These materials are formed by a process which comprises: (a) contacting an amine compound having at least two reactive nitrogen moieties with at least one long chain hydrocarbon-substituted reactant in an amount and under conditions sufficient to form a N-containing polymer adduct containing reactive amine groups, and (b) contacting the N-containing polymer adduct with at least one aromatic N-containing monomer under polymerization conditions to graft said N-containing polymer adduct with aromatic N-containing polymer segments.
