The oscillatory behaviour of neck propagation during cold drawing of polymer films has been studied numerically. Previous calculations based on Barenblatt's model considering the temperature rise at the neck have been refined by introducing heat diffusion and the consequent temperature distribution in the film. Period doubling of the oscillation and other phenomena that were observed experimentally and remained to be explained have been produced by the refined model
