Zusammenfassung:	Disclosed are modified PET polymer compositions and process for making modified PET polymer compositions by reacting purified terephthalic acid and non-hydrogenated isophthalic acid with ethylene glycol. Compositions with acceptable visual appearance, such as clarity and color, can be made at typical modification levels for many packaging application. Disclosed are also shaped articles and the process for making shaped articles of the modified PET polymer composition.
