The Study on Crystallization of Injection Molded Isotactic Polypropylene

摘要：

The crystallinity of injection molded isotactic polypropylene was measured by wide angle X-ray diffraction CWAXD) and the distinct skin-core morphology was visible under a polarizing optical microscope. The results show that the crystallinity and skin-core structure are dependent on the injection molding processing conditions. The crystallinity decreases with the distance from the gate. The skin layer thickness is thinner with the higher injection temperature.
