METHOD OF PREPARING BRIDGE METALLOCENE COMPOUND Russian patent published in 1997 - IPC

FIELD: organic chemistry. SUBSTANCE: (1) double bridge ligand, while reacting with proton acceptor, is transformed into double bridge anion; (2) double anion is transformed into bridge metallocene compound by reaction with compound of 4b, 5b or 6b group metal of periodic system, reaction (II) being carried out in liquid dispersing agent which comprises one or more weak Lewis based the conjugated acids of which have dissociation constants within pK_a of equal or less than 2.5, (b) comprises not greater than 1 mole equivalent with respect to compound of metal, strong Lewis base the conjugated acid of which has pK_a of greater than-2.5. Present invention also describes catalyst component for polymerization of olefins and method of polymerization of olefins and polyolefins. EFFECT: more efficient preparation method. 9 cl
