BEADED POLYMER SUPPORTS AND GELS .1. MANUFACTURING TECHNIQUES

A general review of preparative aspects of beaded polymer supports and gels (microbeads) is presented. Basic features of manufacturing processes employed for the production of beaded organic and inorganic polymers and gels are discussed. Typical procedures for the synthesis of beaded silica, polysaccharides, polyacrylamides, polymethacrylates and polystyrene are described. Preparative aspects of microspherical products based on inorganic-organic composites, interpenetrating networks, pellicular particles, core-shell grafts and recently introduced amphiphilic copolymer resins are also discussed.
