Abstract
The present invention relates to porous cross-linked polymeric particles having cavities joined by interconnecting pores wherein all or nearly all of the cavities at the interior of each particle communicate with the surface of the particle. The present invention also relates to a process for producing a porous, cross-linked large polymeric particle as well as the product of this process. This process involves combining a continuous phase with an aqueous discontinuous phase to form an emulsion, then placing this emulsion into a mold to produce large particles having shapes derived from a mold, e.g., ellipsoids, spheroids, cylinders, prisms, etc. Also included in the invention are modifications of the particles as well as methods for using the particles in a variety of applications. All described methods, compositions, and articles of manufacture are within the scope of the invention.
