Abstract
Pulse radiolysis investigation was carried out on solutions of styrene in 2-methyltetrahydrofuran and n-butyl chloride with 1.0-μsec electron pulses (15 Mev) at room temperature. Styryl radicals and radical anions formed from the solute were observed from the former solution. In addition to the styryl radicals, the absorption band (λmax=350 nm) of cation radicals was observed in the n-butyl chloride solution. These radicals are formed by the positive charge transfer from the solvent to the solute styrene, and disappear mainly with the 2nd order kinetics by recombining with anionic intermediates. However, in the later period, their decay deviates from the 2nd order kinetics. This results from the superposing 1st order reaction with rate constant of about 2×106 mol−1l sec−1, probably due to the addition of styrene to the radical cations. These results are discussed with respect to the initiation process in radiation-induced cationic polymerization of styrene.
