  • Methods for synthesis of end-functionalized polyolefins
    Patent number: 10414903
    Abstract: A strategy for the synthesis of semi-telechelic polyethylene through the palladium diimine-catalyzed chain transfer polymerization of ethylene using various silanes as chain transfer agents is reported. Polymer molecular weight and end-group chemical structure can be tuned by varying the chain transfer agent as well as its concentration. NMR spectroscopy confirms that the silicon of the chain transfer agent is incorporated into the polymer. The stability of the catalyst toward polar monomer enables the chain transfer polymerization of semi-telechelic poly(ethylene-methyl acrylate) copolymers.
    Type: Grant
    Filed: November 10, 2017
    Date of Patent: September 17, 2019
    Assignee: The Board of Trustees of the University of Illinois
