Abstract

Abstract: A titanium Schiff-base complex having two phenoxy-imine chelate ligands combined with Al(i-Bu)3 has high catalytic performance for the polymerization of n-octylallene. The complex [Ti(Salen)2Cl2] was synthesized with high yield by reacting the Schiff-base ligand with TiCl4 in n-hexane. The optimum reaction conditions for the polymerization are: n(M)/n(Ti)=100, n(Al)/n(Ti)=50, aged at 80 ℃ for 1 h, polymerized at 80 ℃ for 16 h in bulk, and the poly-n-octylallene obtained has 100% yield, Mw=1.1×105, MWD=1.77 and 50% 1,2-polymerized units.

Key words: Titanium Schiff-base complex, n-Octylallene, Polymerization
