Abstract
According to one aspect, the present invention relates to a low-density polyethylene having a melt index MFRof 2.5 to 10.0 g/10 min, a density of 910 to 935 kg/m, and a dynamic viscosity ηat a shear rate of 0.05 rad/s and a dynamic viscosity ηat a shear rate of 300 rad/s which satisfy the following relationship:η≦108 Pa*s+0.0253*η. According to a second aspect, the present invention relates to a low-density polyethylene having a melt index MFRof 2.5 to 10.0 g/10 min, a density of 910 to 935 kg/m, and a phase shift δat a frequency of 0.5 rad/s and a phase shift δat a frequency of 300 rad/s, which satisfy the following relationship:tan δ≧0.45+0.164*tan δ.
