Emulsion-based Free-Radical Retrograde-Precipitation Polymerization

This monograph is a follow-up to the first FRPPP book by Gerard Caneba. It includes additional conceptual results, implementation of the FRRPP process in emulsion media to produce various block copolymers, and other FRRPP-related supplementary topics.

This monograph is a follow-up material to the first FRRPP book by Gerard Caneba in 2009. It includes additional conceptual results, implementation of the FRRPP process in emulsion media to produce various block copolymers, and other FRRPP-related supplementary topics. Conceptual topics include the application of the quantitative analysis presented in the first FRRPP monograph for the occurrence of the FRRPP process to the polysterene-styrene-ether (PS-S-Ether) and poly(methacrylic acid)-methacrylic acid-water (PMAA-MAA-Water) systems, as well as extensions through unsteady state analysis of the occurrence of flat temperature profiles. 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. Topics in implementation of the FRRPP process from pre-emulsions of monomers and the solvent/precipitant are highlighted. Additional FRRPP topics are included in this monograph that pertain to more recent efforts of Gerard Caneba, such as oil spill control, oil dispersant system, and caustic sludge remediation from emulsion-based FRRPP materials, hydrolysis of vinyl acetate-acrylic acid-based copolymers, and other polymer modification studies from FRRPP-based emulsions.

Summarizes for the first time the emulsion-based free-radical retrograde-precipitation polymerization in one book Written by experts in the field, one from academia, one from the industry Application oriented Includes supplementary material: sn.pub/extras
