Preface

This monograph is a follow-up material to the first FRPPP book by Prof. Gerard T. Caneba in 2010. It includes three parts that are related to one another, i.e., they are applicable to emulsion-based systems and they point to the importance of the consideration of the densification phenomenon that occurs in FRRPP systems. In Part I, additional conceptual results, simulation of dynamic thermal behavior, and conventional emulsion polymerization topics are introduced. Conceptual topics include the application of the quantitative analysis presented in the first FRRPP monograph for the occurrence of the FRRPP process to the polystyrene–styrene– ether (PS–S–Ether) and poly(methacrylic acid)–methacrylic acid–water (PMAA– MAA–Water) systems. Also, the generalization of the quantitative analysis is done to consider molecular weight effects, especially based on changes of the phase envelope to an hourglass type. Part I also includes a substantial analysis of the dynamic thermal behavior of reactive domain FRRPP spherical particles, which is a follow-up from the steady-state analysis of quantitative description of FRRPP behavior introduced in Chap. 2 of the first FRR
