FIELD: chemistry.

SUBSTANCE: invention relates to a pyridyldiamide transition metal complex. The complex is described by general formula (IV), wherein M denotes Ti, Zr or Hf; R₆, R₇, R₈ and R₉ denote hydrogen; R₁ and R₁₁ are independently selected from a group including alkyls and phenyl groups containing 0-5 different substitutes which include F, Cl, Br, I, CF₃, NO₂, alkoxy group, dialkylamino group, hydrocarbyl (such as alkyl or aryl) and substituted hydrocarbyls (such as heteroaryl), containing 0-10 carbon atoms; R₂ and R₁₀ all independently denote -E(R₁₂)(R₁₃)-, where E denotes carbon, and each R₁₂ and R₁₃ is independently selected from a group which includes hydrogen and phenyl groups; R₃, R₄ and R₅ denote hydrogen; L denotes an anionic splitting group, wherein the L groups may be identical or different and any of the two L groups may be bonded to form a dianionic splitting group; n equals 0, 1, 2, 3 or 4; L' is selected from a group which includes ethers, thioethers, amines, nitriles, imines, pyridines and phosphines; and w equals 0, 1, 2, 3 or 4. Also disclosed are methods of producing the complex (versions), pyridyldiamine for producing the complex, a catalyst system and a polymerisation method.

EFFECT: invention enables to obtain novel pyridyldiamide transition metal complexes which can be used in polymerisation of alkenes.
