Abstract
This invention relates to polymer compositions containing naphthalenedicarboxylic acid residues and having reduced fluorescence due to the presence of aromatic thioether compounds. More specifically, the polymer compositions contain poly(ethylene 2,6-naphthalene dicarboxylate) and 0.1 to 5 mole percent of an aromatic thioether compound. The pollers are useful for packaging applications where clarity and/or aesthetic appeal is important.
