Nematic order high-temperature glassy nematics

The same situation prevails for PLCs. Depending on their chemical structure, semicrystalline states may or may not be obtained. However, owing to the occurrence for these polymers of nematic and/or smectic phases, either the whole material or only the non-crystalline parts of the material will yield an ordered glassy state characterized by a glass transition temperature, Tg (ordered). Such a situation is achieved by cooling the polymer slowly from the high-temperature isotropic state. Of course, if no orientation procedure has been applied, a multidomain sample is obtained.
