How is polystyrene synthesized
Web29 jul. 2024 · The particle size and distribution were obtained by adding the initiators to the TMC-1 sample. PSMA was synthesized by stirring at a speed of 250 rpm for 6 h at 70 °C. The observed morphological changes caused by the initiator are shown in Figure 2 and Figures S4 and S5. Increasing the amount of AIBN and KPS decreased the particle size. http://polymerdatabase.com/polymer%20chemistry/Polystyrene.html
