The telomerization of methyl acetate with ethylene, using di-tert.-butyl peroxide, benzoyl peroxide, or azo-bis-iso-butyronitrile as initiator, has been studied. Experimental results show that di-tert.-butyl peroxide is much more efficient than benzoyl peroxide and azo-bis-iso-butyronitrile. For each of the three initiators mentioned, within the range from 0.12 to 4.6 moles of initiator for every mole of methyl acetate, the yield of the telomeric products increases almost linearly with the increase in the amount of the initiator used.
