This paper concerns the recent progress in our search for new initiating systems for living cationic polymerization and the mechanisms involved therein, specifically focusing on: (a) Protonic acid/Lewis acid initiating systems for vinyl ethers; (b) Initiating systems for living cationic polymerization of styrene; (c) Multi-functional initiating systems.In area (a), the design of counteranions was discussed relative to the principles of living cationic polymerization; in area (b), the first truly living cationic polymerization of styrene is described; and in area (c), the multi-functional initiating systems led to tri-armed polymers of vinyl ethers and p-alkoxystyrenes with amphiphilic arm chains of uniform lengths.
