Tunning the Porosity of Polystyrene-Base Beads with Well-Defind PorogenSynthesized via RAFT Polymerization

Porogens are the key to create porous nature of the polymer beads. Various solvents, polymers oroligomers can be used as the porogen to create porosity in polymer particles during the suspensionpolymerization process. The morphology, specific surface area, pore volume, and size distribution ofpores depend on the type of porogen. Polymer particles with monodisperse porosities have beendeveloped for applications such as separation media and selective adsorbents. To prepare theseparticles, the controlled radical polymerization process (RAFT) was utilized to synthesize linearpolystyrene as a porogen. This process can control the weight and molecular weight distribution ofthe polymer, leading to the creation of polystyrene with a well-defined structure.
