Abstract : The report contains results on the polymerization or attempted polymerization of the following monomers by gamma radiation (7.6 rads/hr.) at reduced temperatures: acrylonitrile, hexafluoropropylene, fumaronitrile, hexafluoroacetone, trifluoroacetaldehyde, perfluorooctanal, and pentafluoropropionaldehyde. A comprehensive bibliography on the gamma irradiation of potential monomers was almost completed, and a preliminary listing is included. In addition, a Differential Thermal Analysis assembly was constructed for use during polymerization by gamma radiation of acrylonitrile. The results qualitatively indicate that polymerization occurs only in the temperature vicinity of a phase transition. (Author)
