FIELD: metalloorganic chemistry, polymers, chemical technology.
SUBSTANCE: invention describes metallocene compound of the formula (I): LGZMXp wherein L represents bivalent group; Z represents residue of the formula (II) given in the invention description wherein R3 and R4 are taken among hydrogen atom and hydrocarbon groups; A and B are taken among sulfur atom (S) or CH being if A means sulfur atom (S) then B means CH; if B means sulfur atom (S) then A means CH; G represents residue of the formula (III) ![](/patent/RU2243229C2/i/00000192.png)
wherein R6, R7, R8 and R9 are taken among hydrogen atom and hydrocarbon groups; M represents transient metal atom: zirconium or hafnium; X is taken among halogen atom or (C1-C6)-alkyl; p is a whole number from 0 to 3. Also, invention describes ligands for these metallocenes and methods for their preparing. Metallocenes of the formula (I) are used in catalysts in carrying out a method for synthesis of polymers of alpha-olefins, especially propylene polymers with low degree of crystallinity.
EFFECT: improved preparing methods, valuable chemical properties of compounds.
