  • Process for preparing styrene polymers
    Patent number: 5587438
    Abstract: The invention relates to a process for preparing polymers by bulk polymerizing a monomer feedstock composed of styrene or styrene-like monomers and/or anionically copolymerizable comonomers employing an anionic initiator and a conventional spray-tower as reactor in the absence of a quenching solvent that fills the lower portion of the spray-tower, and the polymers so produced.
    Type: Grant
    Filed: May 31, 1995
    Date of Patent: December 24, 1996
    Assignee: Shell Oil Company
    Inventors: Frederik L. Binsbergen, Alouisius N. R. Bos, Augustinus Santen
  • Anionic extruder polymerization process
    Patent number: 5229472
    Abstract: An improved process for the anionic extruder polymerization of ethylenically unsaturated compounds in the presence of an organoalkali metal compound initiator employs relatively high reaction temperatures but relatively short residence times in the extruder.
    Type: Grant
    Filed: June 11, 1992
    Date of Patent: July 20, 1993
    Assignee: Shell Oil Company
