In order to obtain more information on molecular mechanisms for three relaxations in the γ-loss band in linear polyethylene, the effect of the treatment with HNO_3. at 80℃ on the magnitude of the loss tangent associated with these relaxations is investigated. Values of the loss tangent for polyethylene are calculated from those for a composite solid made of polystyrene and polyethylene powder treated variously. For this purpose an extension of the applicability of the empirical formula proposed by Gray and McCrum is examined. It is evident that theγ_1 and the γ_2-relaxations decrease and the γ_3-relaxation increases in magnitude with increase in the treatment time. From these results the γ_3-relaxation is attributed to the motion of cilia which is increased by the treatment, while the other two relaxations are attributed to the motion of folds or other interlamellar amorphous parts.
