Unique pathway : The radical‐initiated addition polymerization of MesP=CPh 2 propagates through the ortho ‐bound CH 3 group of the Mes moiety after CH bond activation (see scheme, Mes=2,4,6‐trimethylphenyl, tht=tetrahydrothiophene, TEMPO=2,2,6,6‐tetramethyl‐l‐piperidinoxyl). This unique isomerization polymerization mechanism contrasts the previously suggested head‐to‐tail enchainment typically observed for olefins.
