Cellulose ester derivatives and a process for the production thereof

摘要

Novel cellulose ester derivatives having good solubility which are useful for coating agent, thickening agent, protective colloid, etc.; and a method for the preparation of said cellulose ester derivatives wherein cellulose is reacted with a specific lactone such as glycolide, lactide or epsilon -caprolactone in a solvent and in the presence of a catalyst for esterification.
