Abstract

The 1,4-di-(2-chloro-2-propyl)-benzene (pDCC)/BCl3/IB system was investigated in the presence and absence of n-Bu4NX. The presence of n-Bu4NX (X=Cl or I) changes the mechanism increasing the living character of the polymerization of isobutylene in both cases. When n-Bu4NCl is added, BCl4- is formed and as a common ion in excess it shifts the dissociation equilibrium toward the non-dissociated species. In the case of the addition of n-Bu4NI, an exchange reaction between the gegenions, i.e., BCl4- and BCl3I- has been recognised and a possible reaction mechanism is given.
