High clarity low haze compositions

A film formed from 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=2145−2216*FractionLMW−181* a molecular weight distribution of the LMW component (MWDLMW)−932*a molecular weight distribution of the HMW component(MWDHMW)+27*(FractionLMW*MWDLMW)+1019*(FractionLMW*MWDHMW)+73*(MWDLMW*MWDHMW) wherein fraction refers to the weight fraction of the component in the polymer as a whole.

A process for producing a bimodal polymer comprising:

• contacting a polymerization catalyst and monomer in the presence of hydrogen in one or more polymerization reactors to yield the bimodal polymer,
• wherein the bimodal polymer has 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 =2145−2216*FractionLMW−181*a molecular weight distribution of the LMW component (MWDLMW)−932*a molecular weight distribution of the HMW component(MWDHMW)+27*(FractionLMW*MWDLMW)+1019*(FractionLMW*MWDHMW)+73*(MWDLMW*MWDHMW) wherein fraction refers to the weight fraction of the component in the polymer as a whole.
