Title
(EN) POLYETHYLENE COMPOSITION OF IMPROVED PROCESSABILITY
(KO) 개선된 가공성의 폴리에틸렌 조성물
Abstract
(EN)
The present invention relates to a polyethylene composition, comprising a base resin which comprises (i) a first fraction which is an ethylene homo-or copolymer, and (ii) a second fraction which is an ethylene copolymer, wherein the first fraction (i) has a lower weight average molecular weight than the second fraction (ii), and the base resin has a density of less than 0.940 g/cm^3 and a shear thinning index SHI2.7/210 of at least 25. ©KIPO&WIPO 2008
