One-step seeded polymerization was used to prepare 7∼10 μm of crosslinked monodisperse spheres with four crosslinking agents using 4.68 μm poly(methyl methacrylate) (PMMA) seed particles in aqueous-alcoholic media in the absence of the swelling process. The crosslinking agents used were ethylene glycol dimethacrylate (EGDMA), allyl methacrylate (AMA), 1,6-hexanediol diacrylate (HDDA) and trimethylolpropane trimethacrylate (TMPTMA). The effects of the type and concentration of the crosslinking agents on the swelling, pore size, thermal property of the networks and morphology of the particles were studied. The chemical structures and concentrations of the crosslinking agents affected both the swelling ratio and the porosity of the networks. In addition, the chemistry of the reactive vinyl group and chain length of the crosslinking agents affected the stability of the monodisperse particles of the ultimate morphology.
