Abstract
Carboxyalkylcellulose esters are disclosed having relatively low degrees of polymerization. These new carboxyalkylcellulose esters include carboxymethylcellulose acetate, carboxymethylcellulose acetate propionate, and carboxymethylcellulose acetate butyrate. The inventive esters exhibit solubility in a range of organic solvents, and are useful in coatings and ink compositions as binder resins and rheology modifiers.
