3 deals with the different heterogeneous polymerization techniques and the main features related to morphology control. 4 discusses briefly the characterization techniques, as any work in this area relies on the need to adequately characterize particle morphology. 2 Equilibrium and Nonequilibrium Morphologies The formation of core-shell particles is a challenging issue of polymer reaction engineering in dispersed media. 1) i=1 j=1 j≠i where aij and σij are, respectively, the interfacial area and the interfacial tension between phases i and j.
This also includes some works in which the first-stage polymer seeds were synthesized via miniemulsion polymeri zation and the second-stage monomer polymerization was performed via emulsion polymerization. 1 Synthesis of Core-Shell Particles (CS) In this strategy the second-stage polymer should build up upon the surface of the seed particles, forming a uniform and continuous and, consequently, concentric shell. As a consequence, CS particles may be formed independently of this being the equilibrium morphology.
