Zhi-gang SHEN, Shang-an LIN. Development of Catalysts for Syndiotactic Polymerization of Styrene[J]. Polymer Bulletin, 2002,15(3):45-51,68. DOI: 10.14028/j.cnki.1003-3726.2002.03.007.
The current development of catalysts used for syndiotactic polymerization of styrene has been reviewed.This paper focused on some high active catalysts including cyclopentadienyltitanium
indenyltitanium
fused-ring titanium
fluorinated-titanium and non-metallocene titanium.The different activity of catalysts was explained with the electron and steric effect of substitunents and the stability of active species.
