Naphthalene dicarboxylic acids and esters substituted with aroyl groups

摘要

This invention relates to naphthalene dicarboxylic acids or naphthalene dicarboxylic esters substituted with aroyl groups. More particularly, this invention relates to the following compounds: dialkyl 1-benzoyl-2,6-naphthalene dicarboxylate, 7-C1-C8-alkoxycarbonyl-1-C1-Cs-alkoxy-l-aryl(1,3-H2 naphtho {1,2-c} furan-3-ones), and dialkyl 1-(2-naphthoyl)-2,6-naphthalene dicarboxylate. The compounds are useful in any polymer composition where dicarboxylic acids or dicarboxylic esters are used especially in poly(ethylene 2,6-naphthalene dicarboxylate) compositions where reduced fluorescence is desired.
