  • Method for reducing the monomer content in acrylonitrile containing polymers
    Patent number: 4537734
    Abstract: The monomer content in acrylonitrile containing polymers, as for example bottles formed from acrylonitrile/styrene copolymer, is substantially reduced by applying ionizing radiation at conventional rates in low dosage levels.
    Type: Grant
    Filed: March 12, 1979
    Date of Patent: August 27, 1985
    Assignee: Radiation Dynamics, Inc.
    Inventor: Kennard H. Morganstern
  • Method for reducing the monomer residue content in polymer plastics
    Patent number: 4278518
    Abstract: The monomer content in chlorinated hydrocarbon plastic materials, as for example articles made from polymers of chloroprene vinyl chloride and vinylidene chloride, is substantially reduced by applying ionizing radiation in low dosage levels, e.g. 0.05-2 megarad to the material, either to the fully formed article, or the pellets from which the articles are molded or to the ground resin powder from which the pellets are formed.
