Abstract
Radicals produced in Co60 irradiated normal and 1,1d2‐polypropylene have been examined by electron spin resonance. It is concluded that 80% of the radicals are CH2CH(CH2.)and 20% are CH2C(CH3)CH2 in both atactic and isotactic polymer. In the isotactic, but not in the atactic material, the primary radical disappears much faster than the secondary one when heated. Interpretation of the spectra of polybutylene and polyisobutylene is also given.Keywords
