The electron spin resonance method was employed to study the nature, concentration and kinetics of the disappearance under varying conditions of radicals produced in polyethylene by fast electron irradiation at 77°K. The predominant radical species at 77°K is the alkyl radical —CH 2 —ĊH—CH 2 —. On being warmed to room temperature it disappears rapidly, revealing a more stable un­identified radical. The kinetics of the decay at room temperature of both radicals was observed. Their stabilities were found to vary in polyethylene samples of differing physical and chemical properties. G values for these radicals are given. Comparison was made with spectra obtained under similar conditions with two pure paraffins and a pure olefin to evaluate the effect of crystallinity branching, molecular weight and unsaturation. In the olefin there is evidence for a build-up of allyl radicals due to the encounter of an alkyl radical with main chain unsaturation. This supports the view that alkyl radicals are mobile, and cross-linking occurs when two such radicals meet.

The detailed kinetics involved in the photoinitiated addition of n-butyl mercaptan to 1-pentene is presented. It has been shown that side reactions such as propagation and α-dehydrogenation are relatively negligible and the principal mechanism comprises attack by thiyl radical followed by transfer with mercaptan by the alkyl radical. The velocity constant of the attack step is estimated to be 7 × 106 and that of the transfer step 1.4 × 106 liters/mole-sec. These values together with approximate termination velocity constants are shown to explain the kinetics over a wide range of concentration.
