✦ Synopsis
The effect of water on the cationic polymerization of isohutylene by AIEtCI, in n-heptane has been studied. The condition of complete polymerization inhibition is attained a t [H,O] 5 mol/l. Slow polymerization with an induction period is detected a t [H,O]/[AIEtCI,] 5 1. By means of 2,6-DTBP and 0, two mechanisms of initiation proceeding a t the same time have been found: a cocatalytic mechanism and direct catalysis by means of a single-electron transfer from isohutylene to AIEtCI,. The possibility of the control of the reaction is shown.
