Pulsed Initiation Polymerization as a Means of Obtaining Propagation Rate Coefficients in Free-Radical Polymerizations

Abstract The knowledge of kinetic coefficients in polymerization is of paramount importance for the modern production of polymers. Not only the rate of reaction of a polymerization is determined by the kinetics, but also the molecular weight (Mw) distribution and, in copolymerization, the chemical composition distribution.

Historical Overview of (Mini)emulsion Polymerizations and Preparation of Hybrid Latex Particles

In this introductory chapter, a brief overview of emulsion polymerization and miniemulsion polymerization principles is given in relation to preparation of hybrid latex particles. An account is presented of the early history of preparation of hybrid latex particles with an emphasis on the hybrid lattices containing organic and inorganic material phases. The two approaches for obtaining encapsulated inorganic particles are discussed: the chemical method in which polymerization takes place in the presence of inorganic particles, and the physical method whereby latex particles are deposited on the surface of inorganic particles by heterocoagulation. A new classification scheme for the preparation of hybrid latex particles and corresponding higher-order nanostructures is given in this paper. This classification is partially based on a discussion during the International Polymer Colloids Group meeting in Italy in 2009.
