Two kinds of the trisiloxane‐bridged dinuclear titanium metallocene‐type complexes were synthesized. They are monocyclopentadienyl and biscyclopentadienyl dinuclear titanocenes with trisiloxane bridges. The above complexes with modified methylaluminoxane (MMAO) cocatalyst initiate the polymerizations of ethylene and styrene to produce high‐density polyethylene and syndiotactic polystyrene. In addition, a copolymer of ethylene and styrene was obtained.
