  • RAFT polymers
    Patent number: 9650450
    Abstract: The invention provides for a process for removing thiocarbonylthio groups from polymer prepared by RAFT polymerization, the process comprising: introducing into a flow reactor a solution comprising the RAFT polymer in solvent; and promoting a reaction within the flow reactor that removes the thiocarbonylthio groups so as to form a solution that flows out of the reactor comprising the RAFT polymer absent the thiocarbonylthio groups.
    Type: Grant
    Filed: December 14, 2012
    Date of Patent: May 16, 2017
    Assignee: COMMONWEALTH SCIENTIFIC AND INDUSTRIAL RESEARCH ORGANISATION
    Inventors: John Chiefari, Christian Hornung, Almar Postma, Simon Saubern
  • Continuous flow polymerisation process
    Patent number: 8946360
    Abstract: The present invention relates to a process for continuously preparing polymer by RAFT solution polymerization, the process comprising: introducing into a flow reactor a reaction solution comprising one or more ethylenically unsaturated monomers, RAFT agent, non-reactive solvent and free radical initiator; and promoting RAFT polymerization of the one or more ethylenically unsaturated monomers within the reactor so as to form a polymer solution that flows out of the reactor.
    Type: Grant

  • Agonists and antagonists of 5h3-like receptors of invertebrates as pesticides
    Publication number: 20050054680
    Abstract: The present invention provides compositions and methods for controlling an helminth or arthropod pest. In a preferred embodiment of the invention provided herein, the compositions comprise compounds which alter the 5-HT3 receptor of the pest. Also claimed are various esters of N-methyl 8-azabicyclo[3.2.1]octan-3-ol (tropan-3-yl esters) and an assay for identifying and/or assessing a helminth and/or arthropod control compound by determining the ability of a candidate compound to modulate the activity of a helminth or arthropod 5-HT3 receptor.
