A process is described for making emulsions, and microcapsules derived from them, of known, narrow particle size distribution. This can greatly reduce problems of thermodynamic instability and degradation, and improve biological performance by permitting close control of the release rate of capsules
Plastisols of poly(vinyl chloride), PVC, are suspensions of fine particles in plasticizer with about 50% resin volume fraction. Typically, the gross particle size ranges from 15 to 0.2 &mgrm and smaller, where the common practice of spray-drying these resins and subsequent grinding of larger particl
A well-known, but quite inefficient, representation of dead time in a continuous process is that of a series of staged vessels with equal time constants. Buckley (1) compares such a series approximation for dead time, TD, with other methods of dead time representation. The transfer function for this
