A PROCESS FOR PREPARING NAPHTHALENEDICARBOXYLIC ACID CONTAINING POLYMER BLENDS HAVING REDUCED FLUORESCENCE

摘要

This invention relates to naphthalenedicarboxylic acid containing polymer compositions having reduced fluorescence. More specifically, the process involves melt blending a naphthalenedicarboxylic acid containing polymer 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.
