High clarity low haze compositions

A polymerization system comprising:

• a catalyst composition;
• and
• 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,
• wherein the catalyst composition cantacts monomer in the presence of hydrogen in one or more polymerization reactors at polymerization conditions sufficient to yied the bimodal polymer.

A polymerization system comprising:

• a first catalyst composition which contacts monomer in the presence of hydrogen in a first polymerization reactor at polymerization conditions sufficient to yield a first polymer product;
• and
• a second catalyst composition which contacts monomer in the presence of hydrogen in a second polymerization reactor at polymerization condition sufficient to yield a second polymer product:
• and
• a bimodal polymer comprising the first polymer product and the second polymer product, 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.
