Abstract:

Studies involving the irradiation of styrene containing 1 silicone oil, acrylic acid, methacrylic acid, methyl acrylate, butyl acrylate, vinyl acetate, or acrylonitrile with a 2 Mev electron beam under various exposure conditions yielded the following conclusions 1 the effect of an additive is a function of dose rate with respect to both relative yield and the molecular weight of the polymer, 2 the molecular weight decreases in general with an increase in dose rate, irrespective of the additive, 3 an additive which significantly increases the yield tends in general to produce somewhat lower molecular weight polymers than do other additives which give lower yields, 4 an additive, as a function of dose rate, may either increase or decrease the yield of polymer obtained by the irradiation-induced polymerization of some vinyl monomers, and 5 the efficiency of the polymerization decreases markedly for the higher dose rates used in this study.
