TL;DR: A methodological survey of microsphere formation and microencapsulation techniques based on solvent extraction/evaporation techniques is presented in this article, where the basic features of solvent extraction and solvent evaporation processes, including droplet formation, droplet/particle stabilization, and solvent removal, are outlined.

TL;DR: In this paper, a systematic description of morphology, physicochemical criteria, functionalization and activation of beaded polymer supports and gels is presented, including polystyrene, polyacrylamides, copoly(styrene-acryamide)s, polysaccharides, polymethacrylates and silica gel.

TL;DR: A methodological survey of preparation of microspheres and microcapsules by suspension cross-linking is presented in this paper, where the formation of small droplets of a polymer solution (or melt) in an immiscible liquid followed by hardening of these droplets by covalent crosslinking, are discussed.

TL;DR: The free radical copolymerization of N -vinyl-2-pyrrolidone (1) with 2,4,5-trichlorophenyl acrylate (2a) was carried out in chlorobenzene, and in the presence of AIBN, at 50° Copolymerisation of 1 with 2-hydroxyethyl methacrylate was also carried out similarly, except that methanol was employed as a solvent as discussed by the authors.

TL;DR: An overview of the subject of biodegradable microcapsular drug delivery systems from a polymer chemist's viewpoint is presented in this paper, where various polymerization and microencapsulation techniques (including emulsion polymerization, interfacial polycondensation, suspension crosslinking, coacer vation/phase separation and solvent evaporation/extraction) are described.
