2020年6月16日 · A comprehensive overview of the fundamentals of emulsion polymerization and related processes is presented with the object of providing theoretical and practical understanding to researchers considering use of these methods for synthesis of polymer colloids across a wide range of applications.

In polymer chemistry, emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomers, and surfactants. The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water.

Emulsion polymerization is a process where a monomer is emulsified into an aqueous solution with a surfactant, forming droplets that polymerize to create polymer particles of controlled size, typically ranging from 50 to 500 nm.

Comprehensive mathematical modeling of an emulsion polymerization process can be done but must include population balances over PSD, polymer chain length distribution, distribution of radicals per particle, copolymer composition distribution, and copolymer sequence distribution.

Emulsion polymerization is an important technological process that is widely used to prepare acrylic polymers, PVC, PVAc, PS, PMMA, PAN, and copolymers of the monomers with butadiene and polychloroprene.

2018年1月17日 · Emulsion polymerization is a polymerization process with different applications on the industrial and academic scale. It involves application of emulsifier to emulsify hydrophobic polymers through aqueous phase by amphipathic emulsifier, then generation of free radicals with either a water or oil soluble initiators.

Emulsion polymerization can handle activated initiation, redox initiation, absorption and desorption, and much of the kinetics described in the free-radical Reaction Kinetic Scheme, but not short chain branching or beta scission.

Emulsion polymers are “products by process” whose main properties are determined during polymerization. A critical point is to know how these process variables affect the final properties of the product. A possibility is to consider the reactor as a black box and to develop empirical relationships between process variables and product properties.

2016年8月5日 · The emulsion-polymerization process results in a latex particle, which is a dispersion of polymer in water. Waterborne coatings that primarily use emulsion polymers are the largest type of coating technology used on a global basis and are expected to continue to grow as a percent of the total coatings market.
