Description
Summary:The syndiotactic polymerization of styrene with methoxyethylcyclopentadienyl titanium trichloride ( 1), 2-tetrahydrofurfurylcyclopentadienyl titanium trichloride ( 2), cyclopentadienyl dichloroisopropoxy titanium ( 3) and methylaluminoxane was studied. Substituted half-sandwich titanocene ( 1, 2) exhibited low activity and syndiotacticity, while the alkoxy derivative of cyclopentadienyl titanium trichloride exhibited high activity and syndiotacticity. Possible reasons for the differences are discussed.
