METHOD FOR OLEFIN POLYMERISATION WITH ADJUSTABLE MORPHOLOGY Russian patent published in 2008 - IPC C08F4/64 C07F17/00 C08F10/00 

FIELD: chemistry.

SUBSTANCE: catalytic composition for olefin polymerisation includes catalytic compound selected out of group including 4^th group metal complexes with one or more ligand π-linked to transition metal, and metal complexes of formula, , where R¹ is selected out of group including alkyl, cycloalkyl, heteroalkyl, cycloheteroalkyl, aryl, and inertly substituted derivatives of the described groups, containing 1 to 30 atoms beside hydrogen, T is bivalent bridge group including 1 to 20 atoms beside hydrogen, R² is C_6-20heteroaryl group including Lewis base functionality, particularly pyridine-2-yl- or substituted pyridine-2-yl-group, M is 4^th group metal, X^e is anion, neutral or dianion ligand group, x is a number from 0 to 5 indicating number of X^e groups, links, optional links and electron donor connections are indicated by lines, dotted lines and arrows respectively; activation agent for transformation of the claimed catalytic compound into active catalyst for additive polymerisation, optional carrier, optional liquid dissolvent and metal hydrocarboxylate additive salt of formula: , where R^e is hydrogen, halogen or C_1-6 alkyl. Invention also claims method of olefin polymerisation using described catalytic composition.

EFFECT: reduced film forming and reactor pollution; improved catalyst properties; improved morphology of polymer particles.
