The effect of continuous slow monomer addition technique on cationic polymerization in liquid sulfur dioxide

  • Published:
Polymer Bulletin Aims and scope Submit manuscript

Summary

The polymerizations of styrene and alpha-methylstyrene in liquid sulfur dioxide have been investigated by the use of the slow, continuous monomer addition technique in the presence of m-chloroperbenzoic acid or CF3SO3H as initiator. Quasiliving polymerization has been obtained in Sty/MCPBA/−40°C/liquid SO2 system. The formed polymer is insoluble in the medium indicating that in liquid SO2 the propagating species remain active even in a heterogeneous system.
