Summary This communication deals with the description and experimentation of an original method for studying the molecular processes of deformation in polymers by means of infrared spectroscopy under high-speed drawing conditions. The equipment is based on the model of an industrial drawing bench which involves the pulling of a continuous tape or yarn between two sets of feed rolls and draw rolls, in combination with a Fourier Transform Infrared spectrometer. Preliminary light-polarized measurements concerned with a linear low density polyethylene have been undertaken. Well-resolved infrared spectra are reported for a sample drawn at a take up velocity Vd=39m/min, with a draw ratio λ=7.8.
