Effect of molecular and processing parameters on the flow-induced crystallization of poly-1-butene. Part 1: Kinetics and morphology

Optical microscopy observations provide information on the quiescent growth rate and the morphology of the crystallites. The effect of the different parameters on the observed transition from an isotropic morphology at low shear rates to a rod-like crystalline structure at high shear rates, could again be explained in terms of polymer chain relaxation.
