The synthesis and analysis of copolyesters based on 1,4: 3,6-dianhydrosorbitol (DAS), ethylene glycol, and terephthalic acid is described. It is shown that these copolyesters present materials stable up to elevated temperatures. The glass transition temperature, Tg, is shown to rise linearly with in
