FIELD: chemistry.
SUBSTANCE: catalyst systems according to claimed invention first of all relate to metallocene catalyst, characterised by optimized load on metal and activator concentration, as well as demonstrating improved efficiency and productivity. In one typical version of claimed invention realisation improved metallocene catalyst system according to claimed invention includes metallocene catalyst, activated with methylaluminoxane, and base material, amount of methylaluminoxane being in range from 3 to 9 mmoles of methylaluminoxane per g of base material, and metallocene is present in amount ranging from 0.01 to 1.0 mmole of metallocene per g of base material.
EFFECT: improved catalyst productivity and reactor efficiency.
