Synthesis of poly(2-hydroxypropyl methacrylate) latex particles via aqueous dispersion polymerization

“…10,[13][14][15][16][17][18][19][20][21][22][23][24] One of the attractive features of non-aqueous dispersion polymerization is the ability to prepare very uniform micrometre-sized latex particles by a simple 'one-shot' batch synthesis. Such latexes are used in a wide range of applications, such as marker particles for immunodiagnostic assays, 25 as synthetic mimics for micro-meteorites in space science applications, [26][27][28][29] as spacers for emulsion films to prevent electrostatic problems, 30 and as calibration standards for flow cytometry and various particle sizing techniques. The mean particle diameter can be varied by adjusting a number of parameters, including the stabilizer type and concentration, the initiator type and concentration, the solvent composition and the reaction temperature.…”

Poly(methylmethacrylate)‐poly(vinyl pyrrolidone) microspheres as drug delivery systems: Indomethacin/cefadroxil loading and in vitro release study

“…In the earlier literature, dispersion polymerization was employed to prepare microparticles for drug delivery applications as well as to prepare nano‐sized conducting polymeric particles 14–17. Even though the spherical shape was maintained, a close look at the SEM image of a single particle indicates the formation of a rough surface, possibly due to the formation of the mixture of linear and crosslinked polymer chains in the microparticles 18…”

Colloidal Stabilizer-Assisted Polymerization-Induced Precipitation Method for Colloidally Stable Polyacid Particles

“…1−3 The resulting latex particles have found their applications such as calibration standards for determination of particle size, 4 as marker particles in immunodiagnostic assays, 5 as synthetic mimics for cosmic dusts, 6 and as spacers for polymer films to prevent electrostatic problems. 7 The dispersion polymerization starts from a homogeneous solution of monomer, free-radical initiator, and colloidal stabilizer. In the process of polymerization, polymers/oligomers grow to a critical chain length, above which the polymers/oligomers cannot dissolve in the medium, and precipitate to form nuclei.…”
