CARBOXYALKYL CELLULOSE ESTERS

摘要

This invention provides certain carboxymethyl cellulose (CMC) esters of higher acids (e.g., CMC acetate propionate, CMC propionate, CMC acetate butyrate, and CMC butyrate). These new ether derivatives of cellulose esters exhibit solubility in a wide range of organic solvents, compatibility with a variety of resins, and ease of dispersion in a waterborne formulation and are useful in coating compositions as binder resins and rheology modifiers.
