Unexpected Effects of Seed Polymer on the Porous Structures of Poly(methyl methacrylate-ethylene glycol dimethacrylate) Particles

Abstract Size monodispersed poly(methyl methacrylate-ethylene glycol dimethacrylate) packing materials were prepared by a multi-step swelling and polymerization method with cyclohexanol or toluene as porogenic solvent. When toluene was applied as a porogen, the seed polymer severely affected the porous structure, while no effect was observed with cyclohexanol compared chromatographically with those prepared by the corresponding suspension polymerization methods.
