Blends of syndiotactic polystyrene (sPS) and isotactic polypropene (iPP) have been prepared using TiCl4/MgCl2/β-diketone-MAO.The influences of Al/Ti ratio and the polymerization temperature on the catalyst activity and the blend composition have been investigated.The catalyst shows a good activity of about 1.5×105 gB/mol Ti·h
and the sPS content can be controlled in the range of 55 wt%~82 wt%.Thermal property and micro- morphology have been studied with differential scanning calorimetry (DSC) and scanning electron microscopy (SEM).
