Substitution degree and fatty chain length influence on structure and properties of fatty acid cellulose esters.

•Homogeneous synthesis of fatty acid cellulose esters (FACEs) with both various substitution degree (DS) and fatty chain lengths.•Chemical, thermal, mechanical and WAXS characterizations of FACES.•Highlighting structure-property relationships of FACEs according to both DS and fatty chain lengths.•Chemical resistance of FACEs to acid and alkali solutions according to concentration and contact time.
