The kinetics of the polymerization of potassium, sodium, and lithium salts of acrylic acid exposed at - 78 ts C to radiation from a Co/ sup 60/ source was studied over a range of temperatures, following both the yield and the molecular weight of the polymer as a function of time. A number of alkalineearth salts of acrylic or methacrylic acid were prepared in the anhydrous or various hydrated forms. The polymerizability of these materials sealed under air and exposed to a dose of 800,000 rads at -- 28 ts C is given. Polymerization kinetics of vinyl stearate purified by repeated recrystallization was studied. (W.L.H.)
