FIELD: metallocene supported catalytic systems not obligatory preliminarily polymerized with use of olefin monomer, preferably ethylene or propylene which may be used in polymerization to isotactic polypropylene. SUBSTANCE: isotactic polypropylene is characterized by molecular weight of approximately 100,000 g/mole or above, melting point of approximately 140 C or higher and granulated morphology. Metallocene supported systems usually possess high catalytic activity and when used in polymerizing reactor ensure process with minimum or without formation of flogs in reaction, polluting fines or clots. EFFECT: higher efficiency. 21 cl, 3 tbl
