Polymer Synthesis by Gamma Radiation

Abstract

Monomers have been polymerized successfully by the action of gamma rays to high molecular weight solids without the employment of elevated temperatures or catalysts. Among the monomers polymerized were ethylene, styrene, methylstyrene, acrylonitrile, and methyl methacrylate. Low molecular weight polyester syrups have been solidified into hard transparent solids without the use of the usual catalysts and accelerators. Some chemical and physical properties of these polymers have been determined. Observed values are compared with the properties of polymers obtained by thermal and catalytic activation. Radiation energies required for causing polymerization have been determined.
