OLEFIN POLYMERISATION CATALYST AND METHOD FOR POLYMERISATION OF OLEFIN USING SAID CATALYST Russian patent published in 2012 - IPC C08F4/642 C08F4/655 C08F4/6592 

FIELD: chemistry.

SUBSTANCE: catalyst contains an organic compound of formula 1, an organometallic compound of formula 2, an organic transition metal compound of formula 3 and aluminoxane. Formula 1: R¹-H or R¹-Q-R¹, where R¹ is a cyclic hydrocarbyl group containing 5-30 carbon atoms and at least 2 conjugated double bonds, and can be unsubstituted or can contain 1-6 substitutes which are selected from alkyl groups containing 1-20 carbon atoms; Q is a divalent group for bridging groups R¹, which is a (CR⁵ ₂)_b group, where the substitute R⁵ is a hydrogen atom, b is an integer from 1 to 4. Formula 2: M¹R² _mR³ _nR⁴ _pR⁶ _q, where M¹ is an element selected from a group consisting of group 1 and 2 elements, R², R³, R⁴ and R⁶ independently denote a hydrocarbyl group containing 1-24 carbon atoms, m, n, p and q are independently equal to 0 or 1, and the sum m+n+p+q is equal to the valence of M¹. Formula 3: M²R⁷ _rX_s, where M² is titanium (Ti), zirconium (Zr) or hafnium (Hf), R⁷ is as defined for R¹, X is a halogen atom, r is equal to 0 or 1, s is equal to 3 or 4, and the sum r+s is equal to the valence of metal M². A method for polymerising olefin is also provided.

EFFECT: invention enables to obtain a catalyst having various catalytic properties in accordance with the combination of its components, and which can easily adjust molecular weight, molecular-weight distribution and composition of the obtained olefin polymer or copolymer.
