✦ Synopsis


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 increasing content of DAS to reach values well above 100°C. Thus, DAS derived from renewable resources is a highly interesting diol component for making technical polyesters.
