Leading national thinking on politics, government & public policy through Open Access research

Strathprints makes available scholarly Open Access content by researchers in the School of Government & Public Policy, based within the Faculty of Humanities & Social Sciences.

Research here is 1st in Scotland for research intensity and spans a wide range of domains. The Department of Politics demonstrates expertise in understanding parties, elections and public opinion, with additional emphases on political economy, institutions and international relations. This international angle is reflected in the European Policies Research Centre (EPRC) which conducts comparative research on public policy. Meanwhile, the Centre for Energy Policy provides independent expertise on energy, working across multidisciplinary groups to shape policy for a low carbon economy.

Abstract

Two different gel-type resins have been prepared by suspension polymerization using 2 wt % divinylbenzene (DVB) with either p-vinylbenzyl chloride (pVBC) or a mixture of VBC isomers (similar to 70% m-; similar to 30% p-). Significant difference in the chlorine content was observed, which was attributed to a more favored hydrolysis process when p-VBC was used. The presence of hydroxyl groups has been confirmed by elemental microanalytical data and solid-state C-13 cross-polarization/magic angle spinning (CP-MAS) nuclear magnetic resonance (NMR) spectra. Hypercrosslinked resins were prepared from both gel-type precursors by treatment with FeCl3, in 1,2-dichloroethane (DCE) at 80 degrees C. The resultant resins showed differences in specific surface area and degree of hydrophilicity. The performance of the hypercrosslinked resins was evaluated in solid-phase extraction (SPE) of polar compounds, and better results were obtained for the hypercrosslinked resin prepared from p-VBC that combines a relatively high specific surface area (908 m(2) g(-1)) and somewhat higher oxygen content (3.96 wt % O).
