“…Less detailed investigations have been made of the effects of various radiations on styrene (30,70,307,308,486,522,544), methyl methacrylate (30,110,116,308,309,486,502,522,544), vinyl acetate (70,110,116,307,308,309,486), acrylonitrile (116, 486, 522), vinyl chloride (110, 453), and methyl acrylate (110,522). In all the reports but one, polymerization resulted, and the products were not noticeably different from those obtained by non-radiation methods.…”
