The spin-trapping technique and electron spin resonance (e.s.r.) spectroscopy were employed to study radicals produced by milling ethylene-propylene (EPM) and ethylene-propylene-diene (EPDM) polymers. Mastication of EPDM polymers on a laboratory micromill at room temperature under nitrogen, and in the presence of 2,4,6-tri-tert-butylnitrosobenzene (TBNB), gave a spin adduct which was identified as an anilino type radical where the trapped radical is tertiary in structure. On the other hand, the milling of EPM copolymers in the presence of TBNB did not give spin-trapped radicals.
