Abstract

Copolymers of poly (ethylene terephthalate)(PET) containing 6-oxy-2-carboxyanthracene (OA) and 6-oxy-2-carboxynaphthalene (ON) structural units are prepared by reactive blending of acetoxyarenecarboxylic acid comonomers with PET. The new copolymers are characterized by 1H and 13C NMR, DSC, dilute solution viscometry, optical microscopy, and wide-angle X-ray diffraction and compared to poly (ethylene terephthalate-co-4- ...
