Summary
The homopolymerization of 3-chlorothietane was accomplished using a variety of cationic initiators. Most successful was bulk polymerization at 0°C with ethyl trifiuoromethanesulfonate as initiator and with rapid stirring of the polymerizing mixture. Poly(3-chlorothietane) undergoes a facile structural rearrangement at 35°C in CD2Cl2, giving at equilibrium a copolymer containing 3-chlorothietane and (chloromethyl)thiirane repeating units in a ratio of approximately 6 to 4.
