Abstract
The mesomorphic form of poly(ethylene terephthalate), present in sampl es drawn at 60 degrees C at a draw ratio of 4, was studied by analysin g the transport properties of dichloromethane vapours. The reduced sor ption with respect to the amorphous sample indicates that the mesophas e is impermeable to the vapours at low activity, and this allows the d etermination of the fraction of mesophase in the drawn samples.
