Emulsion Polymerization. Emulsion polymerization is one of the most important methods for the polymerization of a large number of monomers, like vinyl acetate, vinyl chloride, chloroprene, acrylamide, acrylates, and methacrylates. It is also used for the production of various copolymers, like acrylonitrile-butadiene-styrene (ABS).

To conduct an emulsion polymerization reaction, a siloxane in water emulsion is first formed by rapidly mixing, for example, octamethylcyclotetrasiloxane (35 parts), water (65 parts) and a mixture of dodecylbenzenesulfonic acid (DBSA) and its sodium salt (1 1 2;-4 parts). Particle size is equal to or less than 500 nm in diameter.

Emulsion - Wikipedia

An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable). Emulsions are part of a more general class of two-phase systems of matter called colloids.Although the terms colloid and emulsion are sometimes used interchangeably, emulsion should be used when both phases, dispersed and continuous, are liquids. In an emulsion, one liquid (the dispersed ...

Emulsion Polymerization - an overview | ScienceDirect Topics

Emulsion polymerization involves dispersion of a water-insoluble monomer (e.g., styrenes, alkyl (meth)acrylates, etc.) in water with the aid of emulsifiers, followed by the addition of the water-soluble (e.g., ammonium peroxodisulfate, APS) or oil-soluble (e.g., dibenzoyl peroxide, DBP) initiator. The APS-initiated direct emulsion polymerization is a two-step process (Scheme 5):

Smith-Ewart Theory

Emulsion Polymerization Smith-Ewart Theory. The first qualitative mechanism for emulsion polymerization was suggested by Harkins in 1945. 1,2 He postulated that the main locus of chain growth can be found in the stabilized polymer particles rather than in the large monomer droplets. Based on this assumption, Smith and Ewart developed a quantitative model in the late 1940th. 3,4 This model is ...

Polypeptide nanoparticles were obtained by the miniemulsion polymerization of S-(o-nitrobenzyl)-l-cysteine (NBC) N-carboxyanhydride (NCA). Through process optimization, reaction conditions were identified that allowed the polymerization of the water sensitive NCA to yield nanoparticles of about 220 nm size. Subsequent UV-irradiation of the nanoparticle emulsions caused the in situ removal of ...
