Sequential relaxation as the mechanism of physical ageing in amorphous polymers: Sequential relaxation as the mechanism of physical ageing in amorphous polymers. McCrum, N. G. (Dep. Eng. Sci., Univ. 9003-18-3 is the cas registry number. This chemical is also mentioned in this article. Oxford, Oxford, UK). Polym. Commun., 25(1), 2-4 (English) 1984. CODEN: POCOEF. DOCUMENT TYPE: Journal CA Section: 36 (Physical Properties of Synthetic High Polymers) It was shown by thermal sampling and by L. C. E. Struik-type creep expts. (1978) that the changes brought about by isothermal aging in glassy acrylonitrile-butadiene copolymer [9003-18-3] after a quench occurred in sequence, the shorter relaxation times being first. This induced a distortion in the spectrum: as ageing time increased, the distortion changed, caused the spectrum to change shape. This explanation would account for the observation of a universal creep law by G. Grimvall, J. Kubat, and M. Rigdahl (1976): if a solid exhibited ageing then sequential relaxation could yield spectra in pseudo-equil. of comparable shape, independent of the detailed creep mechanism. .
