Popis:	Atmosphere (including small amounts of moisture or oxygen), dose rate, irradiation cycle or time interval between successive exposures, and temperature are significant-variables or experimental parameters for the irradiation-induced polymerization of vinyl monomers by use of an electron accelerator operating at 2 Mev. The molecular weight of the polymer may be predetermined within limits by appropriate selection of variables. Small amounte, 1%, of another monomer added to styrene may have a pronounced effect on both conversion to polymer and on the molecular weight of the product. The molecular structure of the polymer, moreover, as evaluated by infrared spectroscopy, might vary as a function of atmosphere, including small amounts of moisture and oxygen. (auth)
