Acrylic polymer latex has versatile role in many academic and industrial applications like paint, adhesives, textile, paper industry, concrete, surface coating, synthetic rubber and many ones. Acrylic base polymer latex can be prepared by various polymerization methods like Batch emulsion, Seeded emulsion, Situ miniemulsion, Atom transfer radical, Free radical copolymerization, Pickering miniemulsion, Semi-continuous seeded emulsion, dispersion copolymerization, aqueous suspension polymerization etc. in different solvents i.e. 1,1,2-trichloroethane, water, deionized water, 1,4-dioxane, chloroform, tetra hydro furan, toluene, benzene, nitric acid and so on. Acrylic latexes possessed various properties such as increased particle size which resist centrifugal nature and reduce viscosity of heavy oil, layered coating on steel improve lustre along with flexibility, tensile strength and thermal stability too. Acrylic latexes increase silicon intensity in silicon nanoparticles by controlling pH of emulsion during polymerization and also super paramagnetic behaviour of Fe2O3 nanocomposites latex controlled by pH. In this connection, many researchers have synthesized various acrylic base polymer latex or its composites, investigate its utility in different forms for different purposes to improve properties as required. In this review our main emphasis is to investigate the synthesis, characterisation and application of various acrylate polymer latexes.

“…14c , Fe 2 O 3 @lignosulfonate@polystyrene composite latex particles were prepared through Pickering miniemulsion polymerization. 301 Negatively charged lignosulfonate (−34 mV) and positively charged 23 nm (diameter) γ-Fe 2 O 3 NPs (+45 mV) were combined through electrostatic interactions to modify the amphiphilicity of γ-Fe 2 O 3 and allow its use as Pickering miniemulsion polymerization stabilizers with no need of auxiliary surfactants. After polymerization, latex particles with interesting strawberry-like morphologies and superparamagnetic properties ( M s of 30.9 emu g −1 ) were obtained.…”

“…There are numerous studies in the literature reporting the synthesis of IO-coated polymer particles using this solid-stabilized Pickering emulsion technique. However, the obtained composite particles are generally very large − unless the monomer mixture is emulsified using high-shear devices to form miniemulsion droplets and submicronic latexes. − Furthermore, these processes are difficult to scale up, hampering potential industrial applications. As an alternative approach to the polymerization of Pickering (mini)emulsions, inorganic solids can also be directly employed as “Pickering” stabilizers of conventional emulsion polymerization reactions, replacing molecular surfactants.…”

Iron oxide (IO)-armored poly(methyl methacrylate) and polystyrene latex particles have been synthesized by surfactant-free emulsion polymerization using 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS) as an auxiliary comonomer. The use of pure water as a dispersion medium led to unstable latexes both in the presence and absence of IO nanoparticles. In stark contrast, successful syntheses were achieved with the addition of ethanol (15 vol % based on water) to the suspension medium. Transmission electron microscopy showed well-defined “armored” structures with the IO nanoparticles located at the latex surface, forming the so-called raspberry-like morphology. The reported strategy allowed the preparation of polymer/IO composite particles with up to 96% IO incorporation efficiency and 60% IO coverage of the latex surface. The effect of the nature of the core monomer and the AMPS and IO contents on the polymerization kinetics, particle size, and morphology was studied in detail. The final nanocomposite particles possess superparamagnetic properties with a high magnetic response, enabling their rapid and efficient separation under an external magnetic field. A mechanism for the formation of the IO-armored latexes is proposed.
