POLYMERIZATION IN SUSPENSION WITH HIGH CONTENT OF SOLID PARTICLES Russian patent published in 2004 - IPC

Abstract RU 2221812 C2

FIELD: polymerization processes. SUBSTANCE: invention relates to polymerization of olefin monomers in liquid diluent carried out in loop reaction zone provided with device for continuously discharging suspension product. In particular, monomer, diluent, and catalyst circulate in continuous loop reactor to yield suspension containing liquid diluent and solid polyolefin particles. Concentration of the latter in suspension is maintained above 40% based on the weight of polymer particles and liquid diluent. Suspension product continuously discharged from reactor has elevated concentration compared to that in circulating suspension. EFFECT: increased forced circulation speed. 29 cl, 10 dwg, 1 tbl, 3 ex
