  • Reduction of melt fracture in linear polyethylene
    Patent number: 5210142
    Abstract: Polymer blends of at least one ethylene interpolymer product and at least one linear polyethylene are disclosed. The blends have a shear rate at the point of onset of melt fracture at least about 2 percent higher than that obtained for the linear polyethylene alone. The polymer blends are particularly useful for forming films and tapes wherein the melt fracture of the polymer blend is substantially reduced or eliminated, thereby improving extrudability and fabricated article appearance.
