Biosourced Cyclic and Multicyclic Polyesters Based on 1,4:3,6‐Dianhydrohexitols: Application to Metal Ions Uptake in Aqueous Media
Haythem Bennour,Aurélie Fildier,Saber Chatti,Hans R. Kricheldorf,Mongia Saïd Zina,Raouf Medimagh +5 more
TL;DR: Isosorbide and isomannide are polycondensed in solution with trimesoyl chloride at a concentration of 0.06 mol L-1 for the synthesis of cyclic and multicyclic polyesters as mentioned in this paper.

Polyanhydrides, 5. Thermotropic poly(ester anhydrides) derived from monoalkylthioterephthalic acids, hydroquinone and 4‐hydroxybenzoic acid
TL;DR: In this article, a sanidic type of layer structure with a back-to-back array of the main chains is proposed for poly(ester anhydrides) which form ordered domains with predominantly all-trans conformations.

TL;DR: This paper introduced liquid crystal chirally nematic polyesters with flexible chains, comprising isosorbide, isomannide, and/or isoidide units, which are not crystalline and form stable Grandjean textures which freeze on cooling below glass transition temperature.
