  • Oxyfunctionalization of polyolefins
    Patent number: 6953868
    Abstract: The present invention is a method for oxyfunctionalizing, that is, introducing oxygen functionality to, a polyolefin such as polypropylene and poly(ethylene-alt-propylene). The polyolefin is contacted with an oxygen source such as a persulfate and catalytic amounts of a metal porphyrin complex under mild conditions to yield an oxyfunctionalized polymer that has a polydispersity that is very similar to that of the starting polymer.
    Type: Grant
    Filed: April 26, 2004
    Date of Patent: October 11, 2005
    Assignees: Dow Global Technologies Inc., Regents of the University of Minnesota
