✦ Synopsis

The thermal hehaviour and nansport properties of a therrnotropic semiflexible polyester have heen analysed. The system is polymorphic and the transport properties indicate, rather surprisingly, that the sorption coefficient increases on improving the structural organization of the polymer. A structural model has been suggested, based on the hypothesis that the non-crystalline nematic system is characterized by the fine interpenetration of impermeable nematic domains and less ordered permeable domains.
