| abstract |
THE INVENTION PROVIDES CERTAIN CELLULOSE CARBOXIMETHYL ESTERS (CMC), OF HIGHER ACIDS (e.g. CMC ACETATE PROPIONATE, CMC PROPIONATE, CMC ACETATE SHATTRATE, AND CMC BUTIRATE). SUCH NEW DERIVATIVES OF ETER FROM CELLULOSE ESTERS PRESENT SOLUBILITY IN A WIDE RANGE OF ORGANIC SOLVENTS, COMPATIBILITY WITH DIFFERENT RESINS, AND EASE OF DISPERSION IN A WATERPROOF FORMULATION, AND ARE USED IN COMPOSITIONS OF REVESTIZING RESISTORS AND MODELING. |
