  • Patent number: 8728995
    Abstract: A polyalkenyl succinic anhydride is prepared with low amounts of resinous or chlorinated byproducts in a two-step process whereby a polyalkene is first reacted with an unsaturated organic acid in a thermal ene reaction, followed with exposure to a gaseous halogen in presence of an additional amount of the unsaturated organic acidic reagent. The foregoing process produces a polyisobutenyl succinic anhydride having a high ratio of succinic anhydride functional groups to polyisobutenyl backbone groups. Such a polyisobutenyl succinic anhydride is particular suitable for the production of oil-soluble hydrocarbyl succinimides that have good dispersant properties when added to lubricating oil compositions.

  • Publication number: 20140135451
    Abstract: A method disclosed for making a side-chain dendrimer vesicle. The method includes the steps of: At first, there is provided a random copolymer with a narrow distribution of molecular weights by active polymerization and chemical modification. Then, chemical modification is executed to graft various generations of dendrimers to the random copolymer to provide a side-chain dendritic random copolymer with various generations. Two steps of emulsification are taken to induce macromolecular self-assembling of the side-chain dendritic random copolymer solution to form the macromolecular vesicle. The side-chain dendrimer includes C10˜C18 hydrophobic alkyl chains.
