Abstract
The thermal transitions of liquid crystalline polyesters have been stu died by differential scanning calorimetry and thermooptical microscopy . The physical properties of these thermotropic polyesters, particular ly the glass transition and the crystallization temperatures have been investigated. The influence of the spacer type on the transitions has been considered A glass transition at 64 degrees C was observed of th e polyester with oxyethylenic group as flexible spacer while a glass t ransition could not be observed of the polyester with methylenic group s.
