METALLOCENE COMPOUNDS, CATALYSTS CONTAINING SAID COMPOUNDS, METHOD OF PRODUCING OLEFIN POLYMER USING CATALYSTS AND OLEFIN HOMO- AND COPOLYMERS Russian patent published in 2012 - IPC C08F4/6592 C08F10/06 C07F17/00

Abstract RU 2470035 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a bridge metallocene of general formula 1 where M¹ is a group IVb metal, values of radicals R¹, R², R³, R⁴, R⁴, R¹⁰, R¹¹, R¹¹ and R³⁰⁰ are as indicated in the claim. Methods of polymerising olefins are also provided.

EFFECT: bridge metallocenes are used as polymerisation catalyst components and demonstrate higher efficiency, molecular weight of the olefin polymer and low melt flow rate.
