  • Suspension polymerization process
    Patent number: 3962197
    Abstract: A non-continuous suspension polymerization process for the production of finely-divided, low molecular weight polymeric particles of an aryl monomer is carried out in a heated aqueous suspension media at a polymerization temperature above the glass transition temperature of the desired polymer. The monomer reactants and the polymerization initiator are substantially simultaneously introduced into the heated suspension media at a slow, substantially continuous rate over a time within the range of from 20 to about 85 percent of the total polymerization reaction time. The suspension media is subjected to high-rate shearing throughout the reaction.
    Type: Grant
    Filed: January 2, 1975
    Date of Patent: June 8, 1976
    Assignee: Eastman Kodak Company
    Inventor: Ravi Khanna
  • Electrographic developing composition and process using a fusible, crosslinked binder polymer
    Patent number: 3938992
    Abstract: The present invention relates to an electrographic developing composition containing finely divided carrier particles and finely divided toner particles having incorporated therein a fusible, crosslinked binder polymer. An improved electrographic developing process using such toner particles is also disclosed.
