  • Protected functionalized heterotelechelic polymers and processes for preparing the same
    Patent number: 6107414
    Abstract: Protected, functionalized heterotelechelic polymers, hydrogenated and/or deprotected analogues thereof, and processes to prepare these polymers. Monomers are polymerized using a protected functionalized initiator to form a living polymer, and the living polymer is reacted with an electrophile to form heterotelechelic polymers.
    Type: Grant
    Filed: November 19, 1998
    Date of Patent: August 22, 2000
    Assignee: FMC Corporation
    Inventors: James Anthony Schwindeman, Roderic Paul Quirk, Conrad William Kamienski, deceased
  • Protected functionalized telechelic polymers and processes for making the same
    Patent number: 5965681
    Abstract: Protected, functionalized telechelic polymers, hydrogenated and/or deprotected analogues thereof, and processes to prepare these polymers are disclosed. In the invention, a lithium initiator is added to a compound having at least two independently polymerizable vinyl groups to form a dilithium initiator. Monomer is then added to grow or polymerize polymer arms having living ends and the living ends functionalized.
    Type: Grant
