Separation and characterization of poly(styrene‐co‐acrylonitrile)‐graft‐poly(propylene oxide) polymer stabilizer formed in dispersion polymerization of styrene and acrylonitrile in polyether

“…Paine et al 10 showed that the graft polymer formed in situ was the actual steric stabilizer by dissolution and reprecipitation, and determined the structure of the graft polymer by gel permeation chromatography (GPC). Ionescu et al 11 calculated the graft efficiency of PPO in the dispersion copolymerization of acrylonitrile (AN) and α‐methylstyrene in PPO by elemental analysis of oxygen content; it was proved that the PPO polyether was chemically grafted on the particles rather than physically absorbed on the particles by the solution properties. Liu et al 12 determined the conversion profile of macromonomer poly(ethylene oxide)‐methacrylate by GPC in the dispersion polymerization of styrene (St) in ethanol/water.…”
