摘要：
The effect of bis-2-ethylhexyl phthalate (BEHP) and phenyl triethoxy silane (PES) as donors on the stereospecificity of propylene polymerization catalysis was investigated using a MgCl2-supported TiCl4 catalyst. It is suggested that BEHP plays an important role in the fixation of PES on the MgCl2-supported TiCl4 catalyst, and the fixed PES acts as an effective stereospecificity improver.
