Optimization of Particle size and PDI of emulsion polymerized Polystyrene

This study explores the optimization of particle size and polydispersity index (PDI) in the emulsionpolymerization of polystyrene by systematically varying key parameters: water/alcohol mediumpercentage, PVP percentage, AIBN percentage, and temperature. Experimental results demonstratethat higher water content and lower PVP concentrations lead to smaller and more uniform particlesizes. In contrast, increased AIBN concentrations and elevated temperatures result in larger particleswith slightly higher PDI, indicating greater variability. The findings provide valuable insights intocontrolling the polymerization process to achieve desired polystyrene properties, enhancing itsapplicability in diverse industrial contexts.
