This work presents the results on the preparation of new readily available zirconium-containing arylimine complex catalytic systems and their application together with metallocenes in ethylene polymerization. For this purpose, zirconium complexes with grafted ionic liquid type ligands were synthesized and tested in the ethylene polymerization process. On the other hand, it is known that one of the main industrial catalysts for the polymerization process of ethylene is dicycopentadienyl titanium and zirconium dichloride. Therefore, one of the main objectives of the work is to test the using of the newly synthesized complexes with the industrial Cp2TiCl2 catalyst. The products obtained were identified by various physicochemical methods and it was found that these catalytic systems allow one to control the structure and composition of the products obtained.
