摘要: Abstract Polymeric 2,6-disubstituted phenoxy radicals have been studied by means of the electron spin resonance method. The very small meta-hydrogen coupling constants indicate a linear 1,4-polyether structure. Non-equivalent ortho-coupling are observed. reactivity polyphenoxy in termination reactions is characterized apparent activation energy reaction. Bulky ortho-substituents cause increase energy. It assumed that mechanism reaction consists primary and chain transfer as side
