Zusammenfassung:	Novel hydroxyalkyl methyl cellulose acetate succinates which a) have from 4.0 to less than 10.0 weight percent of succinoyl groups, b) have a weight average molecular weight Mw of from 80,000 Dalton to 350,000 Dalton, and c) exhibit a turbidity of up to 41 NTU as a 1.5 weight percent solution in acetone; and novel hydroxyalkyl methyl cellulose acetate succinates which a) have from 10.0 to 20.0 weight percent of succinoyl groups, b) have a weight average molecular weight Mw of from 80,000 Dalton to 350,000 Dalton, and c) exhibit a turbidity of up to 37 NTU as a 1.5 weight percent solution in acetone are useful for preparing solid dispersion of active ingredients in these hydroxyalkyl methyl cellulose acetate succinates.
