Styrene/1-alkene copolymerization by CpTiCl3-additive initiator systems

Initiator systems resulting from the combination of cyclopentadienyltitanium trichloride (CpTiCl3), ethylaluminium dichloride (EtAlCl2) with and without methylaluminoxane (MAO), were used to initiate styrene (S) homopolymerization and S/1-alkene copolymerization. The CpTiCl3-EtAlCl2 system turned ou...
