摘要：
Esterified cellulose ethers which comprise (i) aliphatic monovalent acyl groups or (ii) groups of the formula C(O) R COOA wherein R is a divalent aliphatic or aromatic hydrocarbon group and A is hydrogen or a cation or (iii) a combination of aliphatic monovalent acyl groups and groups of the formula C(O) R COOA which have a viscosity of up to 2.33 mPa•s measured as a 2.0 wt% solution of the esterified cellulose ether in 0.43 wt% aqueous NaOH at 20 °C and which have a viscosity of up to 13 mPao•s measured as a 10 wt% solution of the esterified cellulose ether in acetone at 20 °C are useful for for preparing solid dispersions comprising drugs.
