Abstract
This invention relates to a poly(ethylene 2,6-naphthalene dicarboxylate) composition having reduced fluorescence. More specifically, the composition contains poly(ethylene 2,6-naphthalene dicarboxylate) with 0.1 to 5 mole percent of a copolymerizable halogen containing aromatic compound. The polyesters are useful for packaging applications where clarity and/or aesthetic appeal are of concern.
