  • Graft functionalized olefin polymer dispersant and uses thereof
    Patent number: 7700684
    Abstract: A novel highly grafted, functionalized olefin polymer is provided comprising the reaction product of a method comprising reacting an acylating agent with a mixture comprising an olefin polymer having a number average molecular weight of between about 5,000 to about 100,000 and a diluent in the presence of a free radical initiator to provide an acylated olefin polymer which is further reacted with a polyamine to provide the grafted functionalized olefin polymer dispersant. Lubricating oil concentrates and compositions containing the highly grafted, functionalized olefin polymer and uses thereof also are provided.
    Type: Grant
    Filed: December 9, 2004
    Date of Patent: April 20, 2010
    Assignee: Afton Chemical Corporation
    Inventors: Joseph S. Bradley, Michael A. Danylo, Yoon Soo Song, Anthony F. Fagan
  • Grafted multi-functional olefin copolymer VI modifiers and uses thereof
    Patent number: 7253231
    Abstract: A novel highly grafted, multi-functional olefin copolymer is provided comprising an additive reaction product of a method comprising reacting acylating agent with an olefin copolymer having a number average molecular weight greater than about 1,000 in the presence of a free radical initiator and essentially free of hydrocarbon solvent in an extruder to provide an olefin copolymer intermediate comprising an acylated olefin copolymer having a degree of grafting (DOG) of at least 0.5 wt. %, which copolymer intermediate's molecular weight is reduced, vacuum stripped of unreacted components, pelletized, dissolved in a neutral oil (preferably with inert gas sparging), and further reacted with a polyamine to provide a grafted multi-functional olefin copolymer viscosity modifier, and lubricating oil concentrates and compositions containing the same and uses thereof.
