Description
In this paper, we describe a phase transition in poly (isobutylene) of various molecular weight under elongating stress. Rheometry and wide angle X-ray diffraction have been performed simultaneously to correlate mechanical and structural properties of the material. The low molecular weight samples did not crystallize under the flow in the range of the strain rates applied. On the other hand, as the molecular weight increases the crystallization is always preceded by a strain of the samples under stretching. (Author) 16 figs., 3 tabs
