Tailoring the pore size of hypercrosslinked polymers

Abstract

We report here a practical method to tailor the pore size of hypercrosslinked poly(divinylbenzene-co-vinylbenzyl chloride) (HCP-DVB-VBC) by adjusting the DVB content in poly(divinylbenzene-co-vinylbenzyl chloride) (DVB-VBC) precursors, and then hypercrosslinking these DVB-VBC precursors. With the DVB content varying from 0–10%, the pore size of HCP-DVB-VBC decreases, the pore size distribution becomes narrower and the micropore volume content increases from 6.82 to 61.90%. When the DVB content is higher than 7%, the HCP-DVB-VBC changes to pure microporous organic polymer.
