The purpose of this paper is to characterize the molecular parameters of a Semicrystalline polymer by means of stress-strain-measurements. At low or moderate draw-ratios, the Gaussian theory of rubberlike elasticity of the amorphous regions allows to calculate the intrinsic birefringence of the amorphous region. At higher draw-ratios the non-Gaussian model makes it possible to define the number of statistical segments for any value of homogeneous draw-ratio, and then to estimate the maximum extensibility of the network chains.
