REGIOSELECTIVELY SUBSTITUTED CELLULOSE ESTERS PRODUCED IN A CARBOXYLATED IONIC LIQUID PROCESS AND PRODUCTS PRODUCED THEREFROM

摘要

This invention relates to novel compositions comprising regioselectively substituted cellulose esters. One aspect of the invention relates to processes for preparing regioselectively substituted cellulose esters from cellulose dissolved in ionic liquids. Another aspect of the invention relates to the utility of regioselectively substituted cellulose esters in applications such as protective and compensation films for liquid crystalline displays.
