  • Polymer foams produced by electron beam radiation
    Patent number: 4378278
    Abstract: A process for forming a polymeric foam comprising mixing a liquid multi-functional acrylate monomer and a liquid nonionic fluoronated alkyl-ester surfactant, foaming the surfactant monomer mixture and passing the foamed surfactant monomer mixture under a source of electron beam radiation to polymerize the monomer into a polymeric foam structure.
    Type: Grant
    Filed: September 28, 1981
    Date of Patent: March 29, 1983
    Assignee: S. C. Johnson & Son, Inc.
    Inventors: James R. Allaway, Daniel R. Bloch, Michael P. Fischer
  • Radiation induced graft polymerization
    Patent number: 4340057
    Abstract: An absorbent material is prepared by treating a substrate with an aqueous monomer dispersion of an acrylate salt and a cross-linking monomer and thereafter irradiating the treated substrate with high energy ionizing radiation to form a cage matrix of the polymer and monomer substrate. The absorbent material can be swelled with a solution containing a volatile additive to dispense said additive over a period of time.
