Until the eighties, it was generally accepted that carbocationic polymerizations were intrinsically “uncontrollable” due to the extreme reactivity of the propagating species (carbenium ions). For ex. the rate constant of propagation for the cationic polymerization of isobutene at -90°C is estimated to be 108 L/mol.sec. In this presentation, the slow but steady progress in controllability of cationic polymerizations, eventually leading to living systems will be described. Selected examples of the use of these polymerizations for the synthesis of well defined polymer structures will be given.
