摘要：

The crystalline morphology of Poly(phenylene sulfide) (PPS) isothermally crystallized from the melt under shear conditions has been investigated by polarized optical microscope (POM) equipped with a CSS450 hot stage. The crystalline morphology of PPS is mainly spherulite and greatly influenced by shear flow field. That is, the shear can cause these spherulite orientations, and the row nucleation structure occurs under shear flow conditions. We ascribe it to the tight aggregation of numerous nuclei in the direction of shear. (C) 2007 Published by Elsevier B.V.
