(TBVE), the polymerizations were conducted under Xanthate 1-HCl adduct/SnCl4 and Xanthate 1 or 2-CF3COOH adduct/EtAlCl2 initiating system in the presence of ethylacetate. Both systems proceeded in living polymerization fashion because the calculated Mn of both poly(IBVE) and poly(TBVE) matches with the Mn polymerized assuming that one polymer chain is formed per one molecule of the Xanthate 1 or 2. The
