This invention relates to polymer compositions containing naphtalenedicarboxylic 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 polymers are useful for packaging applications where clarity and/or aesthetic appeal is important.
Cette invention se rapporte à des compositions polymères contenant des restes d'acide naphtalènedicarboxylique et présentant une fluorescence réduite grâce à la présence de composés de thioéthers aromatiques. Plus spécifiquement, les compositions polymères contiennent un poly(éthylène 2,6-naphtalène dicarboxylate) et 0,1 à 5 % en moles d'un composé de thioéther aromatique. Les polymères sont utilisés dans des applications d'emballages où la transparence et/ou l'aspect esthétique ont de l'importance.
