Synthesis and Characterization of Polymeric Resins Based on Methyl Methacrylate and Divinylbenzene

Márcia Clarisse, Yure Queirós, Celina Barbosa, Luiz Barbosa and Elizabete Lucas

Porous spherical materials can be obtained by suspensions polymerization using a solvent pair. In this work porous resins based on methyl methacrylate and divinylbenzene were synthesized and characterized in terms of apparent density, specific area, pore volume, morphology, and swelling percentage. The results show that the diluents system (toluene/heptane or methylethylketone/cyclohexane) affect significantly the polymer properties. Furthermore, differences in the solubility parameters of the monomers and diluents affect the morphological structure of beads.
