Title (EN) REGIOSELECTIVELY SUBSTITUTED CELLULOSE ESTERS
(FR) ESTERS DE CELLULOSE SUBSTITUÉS DE MANIÈRE RÉGIOSÉLECTIVE
Abstract:
(EN) The present application discloses regioselectively substituted cellulose esters, films made from the regioselectively substituted cellulose esters and methods for making the same. The regioselectively substituted cellulose esters are synthesized using trifluoroacetic anhydride and cellulose with various acyl donors or acyl donor precursors.
(FR) La présente invention concerne des esters de cellulose à substitution régiosélective, des films fabriqués à partir des esters de cellulose à substitution régiosélective et des procédés de fabrication associés. Les esters de cellulose à substitution régiosélective sont synthétisés à partir d'anhydride trifluoroacétique et de cellulose en présence de divers donneurs d'acyle ou de précurseurs donneurs d'acyle.
