It makes the reader aware of the potential commercial use of these recent developments. Suspension polymerization is widely used for the preparation of microsphere and microcapsules for many applications. Vinyl chloride is polymerized via free radical polymerization by suspension, bulk, emulsion, and solution methods. 2 The monomer droplets (size of the order 10-1000 m) are suspended in the liquid phase.
#EMULSION AND SUSPENSION POLYMERIZATION PROFESSIONAL#
This book serves as both a professional reference for experienced researchers and a valuable text for newcomers to the field. Suspension polymerization is a heterogeneous radical polymerization process that uses mechanical agitation to mix a monomer or mixture of monomers in a liquid phase, such as water, while the monomers polymerize, forming spheres of polymer. These polymerization methods lead to the generation of the well delaminated polymer nanocomposites with a wide range of polymer matrices. This book provides a single comprehensive source of information about one of the most important facets of polymer nanocomposites technology: synthesis in emulsion and suspension. Until now, most of the published research has been scattered throughout the literature. There are a number of recent advances in these methods such as the use of reactive surfactants, modified initiators, advanced clay surface modifications, use of a variety of fillers, inverse polymerization, and miniemulsion polymerization methods which have further led the generation of advanced exfoliated nanocomposites.
However, advanced techniques provide a number of advantages as compared to the melt blending and lead to more uniform composites with enhanced properties. This leads to some serious confusion and complications. The differences between these terms are often not clear to students and researchers, and they end up using them interchangeably.
#EMULSION AND SUSPENSION POLYMERIZATION FULL#
The majority of the synthesis are carried out by melt blending which frequently result in the full exfoliation of the filler. Depending on the degree of affinity the resulting mixtures are classified as solutions, suspensions, emulsions or colloids. A large number of polymer matrices were tried and nanocomposites with varying degrees of successes were achieved with these polymer systems. Polymer nanocomposites revolutionized research in the composites area by achieving the nanoscale dispersion of the inorganic filler (clay platelets) in the polymer matrices after suitable surface modifications of the filler phase.
