摘要： Methods for polymerizing polyethylene in a tubular reactor may comprise: compressing ethylene monomer to a. pressure from about 2900 bar to about 3150 bar; introducing the compressed ethylene monomer and a modifier into the tubular reactor having two or more reaction zones, wherein each of the two or more reaction zones independently has a peak zonal temperature within a range of about 180°C to about 300°C; and producing a polyethylene composition having a density of about 0.9320 g/cm3 to about 0.9350 g/cm3 measured by ASTM D1505-18 using sample preparation according to ASTM 02839-16.
