ABSTRACT:
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 water-borne formulation and are useful in coating compositions as binder resins and theology modifiers.
