New representatives of chelate-type titanium(IV) salicylideneaniline complexes with bis(5-methyl-2-furyl)methyl substituents in the aniline fragment are synthesized. In the presence of poly(methylalumoxane), these complexes catalyze ethylene and propylene polymerization. The effect of the position of substituents in the ligands on the activities of the catalysts is studied. High-molecular-weight linear
