| Abstract: | Abstract A number of monomers have been polymerized in the presence of catalytic and higher concentrations of SO2. The addition of t-butyl hydroperoxide greatly accelerates the rate of polymerization. The use of 35SO2 indicates that at catalytic concentrations of SO2 (10?2 mole/liter), only one or two molecules of SO2 are incorporated in the chain, but, at high SO2 concentrations, copolymerization of SO2 with vinyl monomers occurs. |
