Bimodal polyethylene composition and pipe comprising the same

Abstract

The present invention relates to a bimodal polyethylene composition comprising a low molecular weight polyethylene homopolymer fraction and high molecular weight polyethylene copolymer fraction having a C4 to C10 α-olefin comonomer content of 0.25 to 3% mol with respect to the total monomer comprised in the high molecular weight polyethylene comonomer fraction, wherein the content of the low molecular weight polyethylene is from 50 to 60 wt % with respect to the total weight of the bimodal polyethylene composition; and the bimodal polyethylene composition has a soluble fraction according to Temperature Rising Elution Fractionation in 1,2,4-trichlorobenzene with 300 ppm of butylated hydroxytoluene at 150° C. of less than 6 wt %; and a pipe comprising the same.
