Quasi-living Carbocationic Polymerization. Recently, Kennedy et al. (165. 173) developed polymerization systems in which under well-defined conditions (a special manner of continuous mixing of monomer with initiating systems), chain termination and chain transfer to monomer are reversible or avoidable, and for all practical purposes the system behaves as if Rj. and are equal to zero. Fast R was achieved by premixing the ingreaients of the initiating systems. 

Two special issues containing Kennedy s work on the use of sterically hindered amines in carbocationic polymerization (218) and on quasi-living carbocationic polymerization (219) were also published. 

In the course of quasi living carbocationic isobutylene polymerization it is possible to functionalize the polymer at their end groups by quenching with reactive compounds. The various possibilities are shown in Table 6.2.
