Preparation of syndiotactic polystyrene using novel monotitanocene with ortho-substituted phenoxy ligands

Preparation of syndiotactic polystyrene using novel monotitanocene with ortho-substituted phenoxy ligands

Four new Cp*Ti compounds with ortho-substituted phenoxy ligands for the syndio- specific polymerization of styrene were prepared by the reaction of various kinds of ortho- substituted phenol with Cp*TiCl3 in the presence of triethylamine. Their catalytic properties for syndiospecific polymerization...
