Zusammenfassung:	A first embodiment which is a bimodal polymer having a weight fraction of a lower molecular weight (LMW) component ranging from about 0.25 to about 0.45, a weight fraction of a higher molecular weight (HMW) component ranging from about 0.55 to about 0.75 and a density of from about 0.931 g/cc to about 0.955 g/cc which when tested in accordance with ASTM D1003 using a 1 mil test specimen displays a haze characterized by equation: % Haze=2145−2216FractionLMW−181a molecular weight distribution of the LMW component (MWDLMW)−932a molecular weight distribution of the HMW component (MWDHMW)+27(FractionLMWMWDLMW)+1019(FractionLMWMWDHMW)+73(MWDLMW*MWDHMW) wherein fraction refers to the weight fraction of the component in the polymer as a whole.
