    摘要: This invention provides for the production of microspheres in an oil-in-water emulsion process using an emulsifier, whereby solvent removal from the oil phase allows for isolation of discrete microspheres, wherein the release rate of a core material is modified by the use of an alkaline agent, e.g. sodium hydroxide, during the preparation of the microspheres.
