Emulsion Polymerization And Emulsion Polymers Pdf

Isopropenyl acetate IPA is one of the monomers from acetate family having an unsaturation with a methyl group attached to the ethylenic carbon. The unsaturation present in the monomer can be utilized for free radical polymerization. Irrespective of this, IPA is not studied much in emulsion polymer synthesis. In the current study, we report the preparation of emulsion polymers using IPA and other acrylic monomers. Terpolymers of butyl acrylate BA , methyl methacrylate, and IPA were prepared via seeded emulsion polymerization with varying IPA proportions on molar basis. Potassium persulfate was employed as an initiator along with Dowfax 2A1 as surfactant anionic.

Emulsion polymerization

Emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomer , and surfactant. 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. The name "emulsion polymerization" is a misnomer that arises from a historical misconception. The particles are prevented from coagulating with each other because each particle is surrounded by the surfactant 'soap' ; the charge on the surfactant repels other particles electrostatically. When water-soluble polymers are used as stabilizers instead of soap, the repulsion between particles arises because these water-soluble polymers form a 'hairy layer' around a particle that repels other particles, because pushing particles together would involve compressing these chains. Emulsion polymerization is used to make several commercially important polymers.


Emulsion Polymerization and Emulsion Polymers provides an up-to-date treatment of both academic and industrial aspects of the subject in a single self-​contained.

Emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomer, and surfactant. 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. Smith and Ewart arbitrarily divided the mechanism of emulsion polymerization into three stages or intervals. Excess surfactant creates micelles in the water. Eventually the free monomer droplets disappear and all remaining monomer is located in the particles.
