Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Unique pathway</bold>: The radical‐initiated addition polymerization of MesP=CPh₂ propagates through the <italic>ortho</italic>‐bound CH₃ group of the Mes moiety after CH 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.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg22f1qs75" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
