  • Synthesis of arborescent polymers via controlled inimer-type reversible addition-fragmentation chain transfer (RAFT) polymerization
    Patent number: 8883912
    Abstract: Randomly branched polymers, such as homopolymers, copolymers, block copolymers and functionalized polymers are disclosed which may be formed by polymerizing a polymerizable monomer, such as styrene with a dithioester chain transfer agent which includes a polymerizable group. The reaction may be performed in one pot. The randomly branched polymer can have high molecular weight and broad molecular weight distribution.
    Type: Grant
    Filed: August 11, 2009
    Date of Patent: November 11, 2014
    Assignee: University of Akron
    Inventors: Judit Eva Puskas, Andrew John Heidenreich
