Two unexpected phenomena have been observed during the study of the growth of ~t and fl spherulites of a poly(ethylene oxide)-resorcinol complex: an overgrowth rate (denoted as Gi) of the fastest, namely the or-form, along the interface of the r-form, and a transformation of the E-form into the or-form, which propagates as a dynamic front at a constant rate G t. The evidence for these two phenomena is demonstrated, and possible explanations are discussed. Measurements of the two rates, G i and Gt, are also reported.
