Kinetics of Isothermal Crystallization of the Thermotropic Polyester Poly(ethylethylene-4,4-diphenoxyterephthalate)

Differential scanning calorimetry was used to study the isothermal kinetics of three-dimensional ordering formation from the mesophase of the thermotropic polyester poly(ethylethylene-4,4-diphenoxyterephthalate). An Avrami exponent of 4 was found and the measured rates of transformation were related with the efficiency of packing. A nucleation and growth process was assumed in the determination of the temperature coefficient, and the interfacial free energies are discussed in terms of the chain flexibility. This revised version was published online in July 2006 with corrections to the Cover Date.
