摘要：

The kinetics of the isothermal crystallization of a phenylethylhydroquinone, phenylhydroquinone, terephthalic acid nematic liquid crystalline copolyester have been studied by differential scanning calorimetry in the temperature interval 319-325-degrees-C. The polymer is characterized by being highly crystalline in spite of its copolymeric nature. The crystallization process is describable by an Avrami equation. This polymer gives the opportunity of studying a crystallization process for chains in which the crystalline morphology is preformed, due to nematic state ordering, thereby giving a well-defined chain morphology from which to initiate crystallization. This feature can facilitate an unambiguous interpretation of the Avrami parameters.
