A catalyst combination and a process for preparing physically crosslinked recyclable thermoplastic polyolefins of simplified processability. In particular the new catalyst combination and a process are useful and for preparing of super high molecular weight isotactic polymers and copolymers of monomodal Gauss like molecular weight distribution with both linear and cyclic olefinically unsaturated compounds as monomer having isotacticity being within the range of from 15 to 70% of [mmmm] pentad concentration, weight average molecular weight within the range from 300,000 to 4,000,000 gms/mol, polydispersity within the range from 1.4 to 12 and statistic distribution of stereoscopic errors along the polymer chain. The catalyst comprises di-furilphenoxyimine type complexes of transition metals in combination with MAO type activator.

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
