A novel, free-radically polymerizable, contorted monomer was synthesized in two steps from bisphenol A. In a simple precipitation polymerization process making use of solvent as a porogen, homopolymerization of this contorted monomer (SBI-DV) resulted in polymeric networks with surface areas as high as 850 m(2)ig and with SA(micro)/SA(BET), values as high as 0.65. Comparative DVB based polymeric networks produced under similar conditions had equally as high SA(BET) but SA(micro)/SA(BET) values of 0.35. In addition, copolymeric networks were produced using varying molar monomer ratios of SBI-DV/DVB. The degree of microporosity in the resulting copolymeric networks correlated with the amount of SBI-DV used in their formation. (C) 2017 Elsevier Ltd. All rights reserved.
