The Influence of Drawing on the Transport Properties of Gases and Vapors in Polymers

Abstract

It is well established that substantial reduction in the equilibrium sorption and even more drastic reduction in the diffusion rates takes place during drawing of polyethylene. The exact influence of the draw ratio on the transport behavior was recently reported by Williams-Peterlinl and a more general discussion of this effect was presented earlier by Peterlin-Williams-Stannett.2 More recently, Williams-Peterlin3 have demonstrated that drastic decreases in transport behavior do not always accompany drawing. In fact, the extent of decrease in the transport behavior is mainly dependent on the medium in which the material is drawn. Furthermore, under certain drawing conditions the rate of diffusion can be actually increased, i.e., the exact opposite as observed during cold drawing of polyethylene. This increase in transport behavior can be very substantial often several orders of magnitude higher than the undrawn material.
