Methyl methacrylate, benzyl methacrylate, butyl methacrylate, and methacrylic acid can be polymerized by 1, 2, 2‐tetraphenyl‐1, 2‐diphenoxyethane (TPPA), 1, 1, 2, 2‐tetraphenyl‐1, 2‐bis‐(trimethylsiloxy) ethane (TPSA), and 1, 1, 2, 2‐tetraphenyl‐1, 2‐dicyanoethane (TPCA) (1–3). The polymerization with these initiators is characterized by three steps; in the first period oligomers from MMA and initiator radicals are formed by primary radical termination.
