Potentially bio-based aromatic polyesters with a kinked structure based on resorcinol have been successfully prepared.

Abstract
Potentially bio-based aromatic polyesters with a kinked structure based on resorcinol have been successfully prepared. The process involves an optimized reaction between resorcinol and ethylene carbonate: the diol thus obtained was polymerized with several aliphatic and aromatic dicarboxylic acids. The chemical structure and the thermal properties of the new polyesters were analysed in order to find correlations between structure and properties. All the polymers present a high thermal stability and are mainly amorphous, with a wide range of glass transition temperatures, according to the diacid structures. On the basis of the results it is clear that resorcinol, which can be derived from renewable resources, is a potential bio-based aromatic monomer, suitable to prepare amorphous polyesters containing 1,3 substituted aromatic moieties, for coating and packaging applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
