To understand the initiating mechanism of the radical polymerization of methyl methacrylate (MMA) in the presence of porphyrin complexes the interaction of Co porphyrins [5,10,15,20-tetraphenylporphyrin (CoTPP), 5,10,15,20-tetra(4-methoxyphenyl)porphyrin (CoTP(MeO)P), 5,10,15,20-tetra(3-butoxyphenyl)porphyrin (CoTP(BuO)P)] with benzoyl peroxide in chloroform and methyl methacrylate was studied using a spectrophotometric method. Oxidation of these metalloporphyrins leads to the formation of isoporphyrins.
