Measurements of the NMR second moment and mechanical loss tangent for solution-crystallized polyethylene treated with fuming nitric acid at 80℃ for 20 h reveal a relaxiation region around -140℃. The relaxation (correlation-time) spectrum for this relaxation region is in good agreement with that for the γ_3-relaxation, which is one of the component relaxations of the γ-loss band of untreated polyethylene crystallized from the melt or solution. The γ_1 and γ_2 relaxations existing in untreated polyethylene are greatly decreased by this treatment. The observed change in the second moment in the γ_3 region (ca. 1.5 gauss^2), is explained as being due to the rotational motion of part of the ciliary chain on the lamellar surface. It is found that absorbed water changes this relaxation into a new one similar to the γ_2-relaxation.
