SPRAY DRYING PROCESS FOR LOW ASPECT RATIO PARTICLES COMPRISING POLY(METHYL METHACRYLATE)-CO-(METHACRYLIC ACID)

摘要

Embodiments of a spray-drying process for producing low aspect ratio particles of poly[(methyl methacrylate)-co-(methacrylic acid)] (PMMAMA) are disclosed. In some examples, at least 95% of PMMAMA-containing particles made by the process have an aspect ratio 10. The particles may further include an active ingredient and/or an excipient.
