Material characterization
The BET surface areas (SBET), pore volumes, and other structural properties of the adsorbents are listed in Table 1. The pore size dis- tribution of the polymers is illustrated in Fig. 1. The nonpolar porous polymer had a specific surface area of 656.4m2 g−1, implying that the polymer consists of a porous network instead of a conventional gel structure. Nyhus et al. [32] reported that polymerization of meta-DVB and para-DVB with toluene as the porogen resulted in a porous polymer with the specific surface area up to 1000 m2 g−1. N2 adsorption analysis results showed that the pore volume of the polymer was 0.94cm3 g−1, demonstrating the porosity of this
