  • Polyethylene blend component and blends containing the same
    Patent number: 8278393
    Abstract: According to one aspect, the present invention relates to a low-density polyethylene having a melt index MFR2 of 2.5 to 10.0 g/10 min, a density of 910 to 935 kg/m3, and a dynamic viscosity ?0.05 at a shear rate of 0.05 rad/s and a dynamic viscosity ?300 at a shear rate of 300 rad/s which satisfy the following relationship: ?300?108 Pa*s+0.0253*?0.05. According to a second aspect, the present invention relates to a low-density polyethylene having a melt index MFR2 of 2.5 to 10.0 g/10 min, a density of 910 to 935 kg/m3, and a phase shift ?0.5 at a frequency of 0.5 rad/s and a phase shift ?300 at a frequency of 300 rad/s, which satisfy the following relationship: tan ?300?0.45+0.164*tan ?0.5.
