A study of inverse dispersion polymerization of acrylic acid using water-soluble redox initiators

Abstract: Inverse dispersion polymerizations of acrylic acid were conducted by using a water-soluble redox initiation system under both isothermal and nonisothermal conditions. The polymerizations were monitored by measuring residual monomer by highperformance liquid chromatography for isothermal polymerizations or by monitoring the temperature variation inside the dispersion for nonisothermal polymerizations. The aqueous drop behavior was examined throughout the course of polymerization by scanning electron microscopy … Show more

“…In some circumstances, there is evidence to suggest that the polymerization rate is diminished when large amounts of an oil-soluble surfactant are used to stabilize the monomer drops, and that a small amount of polymerization occurs in the oil phase [120]. Redox reactions produce free radicals at relatively low temperatures, which is advantageous when the polymerization is very fast at higher temperatures.…”

“…Otherwise, polymerization would begin before the desired DSD was attained. The actual volumes and concentrations used for the two aqueous solutions affect the rate of viscosity increase in the drops and the polymerization rate [124]. Then aqueous reductant is added to start the reaction [122,121].…”

“…També troben diferencies en el rati de polimerització utilitzant diferents geometries de l'agitador, un agitador més tallant produeix probablement el mateix efecte de ruptura de gotes. [5] C.S. Chern fa una descripció molt detallada dels mecanismes de polimerització en emulsió, al mateix temps fa un recull bibliogràfic molt extens de diferents estudis publicats.…”
