  • Poly(ethyleneoxide) functionalization through alkylation
    Patent number: 9012598
    Abstract: A new and efficient method of functionalizing high molecular weight polymers through alkylation using a metal amide base is described. This novel procedure can also be used to synthesize polymer-based macro-initiators containing radical initiating groups at the chain-ends for synthesis of block copolymers.
    Type: Grant
    Filed: July 19, 2013
    Date of Patent: April 21, 2015
    Assignee: Seeo, Inc.
    Inventors: Kulandaivelu Sivanandan, Hany Basam Eitouni, Yan Li, Russell Clayton Pratt

  • SYNTHESIS OF HIGH MOLECULAR WEIGHT PEO USING NON-METAL INITIATORS
    Publication number: 20130131309
    Abstract: A new synthetic method to prepare high molecular weight poly(ethylene oxide) with a very narrow molecular weight distribution (PDI<1.5) is described. The method involves a metal free initiator system, thus avoiding dangerous, flammable organometallic compounds.
