SLURRY PHASE POLYMERISATION PROCESS Russian patent published in 2017 - IPC C08F10/02 C08F2/18 

FIELD: chemistry.

SUBSTANCE: invention relates to polymerisation of olefin in suspension reactors. Slurry process for polymerisation of ethylene is disclosed. Average polymerisation productivity [kg PE (polyethylene)/kg catalyst] per unit ethylene per 1 h, a1 during operation at any first residence time r1 is less than 1.7(a2r2-a1r1)/(r2-r1), where a2 is average polymerisation productivity [kg PE/kg cata] per unit ethylene per 1 h during operation at any second residence time r2 where r2>r1.

EFFECT: technical result is increased efficiency during operation of reactor at high speed of obtaining polymer per unit volume of reactor.
