Organo-cobalt Porphyrin Mediated Radical Polymerization

Organo-cobalt Porphyrin Mediated Radical Polymerization... 

Kinetic plots for polymerization of vinyl acetate (VAc) initiated by azo radical sources (AIBN and V-70) and mediated by cobalt(ii) tetramesityl porphyrin ((TMP)Co ) in CgDg (Figure 5.16) appear very similar to the corresponding plots for MA polymerization (Figure 5.7). During the induction period radicals that enter solution from the azo radical sources react and are trapped by (TMP)Co as the initially formed organo-cobalt complexes ((TMP)Co-CH(OC(0)CH3)CH3 in a manner that parallel the acrylate...
