Beschreibung
Zusammenfassung:	A polyethylene copolymer comprising ethylene units and C4 to C8 α-olefin comonomer units having the following characteristics: a melt index from about 0.1 to about 15 g/10 min as determined at 190° C. by ASTM D1238 under 2.16 kg and at 190° C.; a density from 0.905 to 0.930 g/cc; a molecular weight distribution from about 1.5 to about 2.7; a Crystallization Elution Fractionation temperature range excluding the first 10% and the last 1% polymer on the temperature scale following the equation: ΔT[° C.]≥−909(density[g/cc])+863; and a lamellar thickness distribution following the equation: F %≥510(density[g/cc]−0.905), where F % is the percentage of lamellar thickness greater than 12 nm.
