Abstract:
A fabricated article made from an ethylene polymer containing less than about 20 ppm aluminum, the polymer having:a) a melt flow ratio, I10/I2, &gE;5.63, b) a molecular weight distribution, Mw/Mn, defined by the equation: Mw/Mn&lE;(I10/I2)âˆ’4.63, andc) a critical shear stress at onset of gross melt fracture greater than about 4Ã—106 dyne/cm2, and d) a single melting point as determined by differential scanning calorimetry between âˆ’30 C. and 150 C.
