文摘
- •
Two C1-symmetric 6-5-6 and 5-5-6 [OSNO]-type titanium (IV) complexes were synthesized and characterized.
- •
The [OSNO]-type titanium complexes can polymerize styrene into syndiotactic polystyrene (sPS) with high syndiotacticity.
- •
The selective chain transfer to the aluminum cocatalyst took place.
- •
The nature of active species was demonstrated to be cationic titanium (III) complexes.
