Abstract
This invention relates to poly(ethylene 2,6-naphthalene dicarboxylate) blends having reduced fluorescence. More specifically, the process involves melt blending poly(ethylene 2,6-naphthalene dicarboxylate) with 0.1 to 5 weight percent of a fluorescence quenching compound selected from a halogen containing aromatic compound, an aromatic ketone or a naphthol compound and thermoforming the blend into an article. The blends are useful for packaging applications where clarity and/or aesthetic appeal are of concern.
