Abstract

Results from in-situ time-resolved SAXS measurement on PEH melt crystallization, subjected to a step shear, indicate that an oriented lamellar structure is formed at the initial crystallization stage upon cessation of the step shear. Randomly distributed lamellae are formed during the late stages. The value of long period estimated along the meridian during the shear-induced crystallization is close to that under the quiescent crystallization condition in PEH.
