The crystallization behavior of α-phenyl o-cresol (o-benzyl phenol) has been investigated over the range of undercooling up to 90 °C. The growth rate reaches a maximum value of about 10-3cm sec-1 at an undercooling of about 30 °C and decreases to about 10-7 cm sec-1 at the lowest temperature of study. The reduced growth rate versus undercooling relation has been constructed, and indicates an interface site factor which increases continuously with increasing undercooling. The logarithm of growth rate × viscosity does not decrease linearly with increasing 1 TδT. The variation of the growth rate with temperature, as well as the corresponding variation of the interface morphology, cannot be described in satisfactory detail by any standard theoretical model. The forms of these variations are in agreement with the predictions of Jackson for materials characterized by large entropies of fusion.
