Graft Copolymerization of Styrene and Acrylonitrile in the Presence of Poly(propylene glycol): Particle Growth

“…This work provides us a better insight into the particle formation and growth in dispersion polymerization. However, the experimental values of the exponent for various dispersion systems often deviate from the theoretical ones to some extent as, $[{\rm Monomer}]_{0}^{- (0.62- 1.02)} \cdot [{\rm Macromer}]_{0}^{- (0.4- 1.17)} \cdot [{\rm Initiator}]_{0}^{- (0.03- 0.1)} $ 17, 18, 27. The possible reason may be ascribed to the very complicated chemical and physical processes in polymerization, such as the breakdown of monodispersity of particle size distribution 12…”

Preparation of Polystyrene/Clay Nanocomposites by Free‐Radical Polymerization in Dispersion

“…The preparation of uniform polymer particles of micrometer size has attracted a great deal of interest 1, 2. Latexes with narrow particle size distribution have found a wide variety of applications, such as in toners, instrument calibration standards, column packing materials for chromatography, solid supports for organic and biopolymer synthesis, and the biochemical field, in biochemical analysis 2–5. These particles are difficult to obtain because their size lies between the size of the particles produced by conventional emulsion polymerization (0.06–0.7 µm) and suspension polymerization (50–1 000 µm).…”

“…Dispersion polymerization may be defined as a type of precipitation polymerization in which the polymerization is carried out in the presence of a suitable polymeric stabilizer, that is, soluble in the reaction medium. The continuous phase is chosen to be a solvent for the monomer to be polymerized and a non‐solvent for the resultant polymer 3, 11, 12. A steric stabilizer is used to produce a colloidally stable dispersion, without which the polymerization would afford macroscopic particles of polymer of uncontrolled size 13.…”
