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 19 mPa·s measured as a 10 wt% solution of the esterified cellulose ether in acetone at 20 °C and which have a weight average molecular weight M of at least 90 000 Dalton are useful for preparing solid dispersions comprising drugs.
