The radioinduced addition of acetaldehyde to isobutylene was found to proceed at room temperature; the G(telomer)'s are smaller by one or two orders of magnitude than those when ethylene or propylene is adopted as the taxogen, and they increase markedly with the temperature, reaching a maximum at 110 approximates 150 deg C. It is shown from the gas chromatographic and NMR analyses of the telomer produced that the radical chain mechanism proposed previously is reasonable, although minor products seem to be formed in accordance to an ionic mechanism. It was found that the G values of all the telomers decrease in the presence of several solid materials, suggesting the catalytic decomposition of acetyl and other intermediate radicals. (P.C.H.)
