摘要：
Disclosed are polymers of hydroxypropyl methyl cellulose acetate succinate (HPMCAS) with unique degrees of substitution of hydroxypropoxy, methoxy, acetyl, and succinoyl groups. When used in making compositions comprising a low-solubility active agent and such polymers, the polymers provide increased aqueous concentrations and/or improved physical stability of the active agent.
