This invention relates to naphthalenedicarboxylic acid containing polymer compositions having reduced fluorescence. More specifically, the polymers contain at least 0.1 mole percent of 2,6-naphthalenedicarboxylic acid or 2,6-naphthalenedicarboxylate ester, with 0.1 to 5 mole percent of a copolymerizable aromatic ketone. These polymers are useful for packaging applications where clarity and/or aesthetic appeal are of concern.
Compositions polymères contenant de l'acide naphtalènedicarboxylique à fluorescence réduite. Plus spécifiquement, lesdits polymères contiennent au moins 0,1 mole pour cent d'acide 2,6-naphtalènedicarboxylique ou d'ester de 2,6-naphtalènedicarboxylate, avec 0,1 à 5 moles pour cent d'une cétone aromatique copolymérisable. Lesdits polymères sont utiles pour les applications d'emballage dans lesquelles la transparence et/ou l'esthétique sont importantes.
