A micro-Raman mapping of the transition region corresponding to the non-oriented to oriented transformation zone in the neck was obtained for stretched poly(vinylidene fluoride) (PVF2). Since Raman spectroscopy is a technique sensitive to the change in the crystalline structure in PVF2 when this polymer is submitted to a stress, the distribution of the crystalline modification along the neck was obtained from the analysis of the micro-Raman mapping. The results show a gradual increase in the degree of crystalline phase transformation along ~ 200/lm in the stretching direction.
