Abstract
In an effort to use trimethylsilyl triflate (TMSOTf) as an initiator for the living polymerization of isobutyl vinyl ether (IBVE) in the presence of Me 2 S the M n versus conversion plot showed a linear relationship for a given solvent. The slope, however, deviated from the calculated one based on an initiator efficiency of 1; i.e., the molecular weights were higher than expected. The addition of water or alcohol increased the initiator efficiency. This result indicated that triflic acid formed by hydrolysis of the TMSOTf was the true initiator
