Emulsion Polymerization

Synthesis Polymer Styrene Butadiene Hybrid Latex with Laponite Organoclay as Filler via Emulsion Polymerization Technique for Application in Paper Coating

“…Typical polymerization monomers formed vinyl monomers structure (CH₂= CH-), as emulsion polymerization is a process involving nucleation step, propagation step and termination step. Stabilization of polymer particles controlled by free radical polymerization mechanism in combination with colloidal phenomena [14,15]. Several emulsion polymerization technique were observed such as conventional emulsion polymerization.…”

“…This emulsion polymerization involved hydrophobic monomers which are emulsified in water and commonly using water soluble initiator such as potassium persulfate [16]. Inverse emulsion polymerization with involved organic solvent with low polarity as polymerization media [14,16]. These two types of emulsion polymerization classified as oil-in-water (o/w) and water-in-oil (w/o) emulsifications [14].…”

“…Inverse emulsion polymerization with involved organic solvent with low polarity as polymerization media [14,16]. These two types of emulsion polymerization classified as oil-in-water (o/w) and water-in-oil (w/o) emulsifications [14]. Mini emulsion polymerization systems involved small monomer droplets in water and usually with 50 nm -1000 nm sizes.…”

“…Particle size of polymer around 10 -50 nm and potassium persulfate initiators were commonly used as initiator [18,19]. The main ingredients of micro polymerization are monomers and water was used as dispersing medium together with water soluble initiator [14,20,21]. When the surfactant level exceeded its critical micelle concentration (CMC), surface tension decrease and forms spherical micelles as result monomers will enter to the vicinity of spherical micelles and reaction continue until all monomer in form of droplets are exhausted and micelles containing monomer increase in size.…”

“…When the surfactant level exceeded its critical micelle concentration (CMC), surface tension decrease and forms spherical micelles as result monomers will enter to the vicinity of spherical micelles and reaction continue until all monomer in form of droplets are exhausted and micelles containing monomer increase in size. Each micelle has dimension in size around 2-10 nm and each micelle containing around 100 -150 surfactant molecules [14]. Usually, radical propagation start when water soluble initiator enter into the micelle, monomer droplets could not compete with micelle in capturing free radicals in aqueous phase due to relative small surface area [12].…”
