ESR study of polyisobutylene radicals produced by γ-irradiation at 77 K

  • 1. Nagoya Inst. of Tech., Japan

Description

An electron spin resonance (ESR) study has been made of radicals trapped in polyisobutylene irradiated at 77 K. It is concluded that only the -C(Me)2-CH- radical remains after heat treatment above 213 K. This radical shows a very sharp doublet ESR spectrum with hyperfine splitting of about 2.2 mT. A broad doublet ESR spectrum observed without warming, which was previously assigned as -C(Me)2-CH- is explained as a mixture of a doublet and a triplet
