Facile synthesis of hypercrosslinked resins via chloromethylation and continuous condensation of simple aryl molecules

Abstract

A sort of non-polystyrene type hypercrosslinked resin was firstly synthesized through chloromethylation of simple aryl molecules (benzene, toluene, naphthalene, diphenyl), succedent continuous Friedel-Crafts alkylation polymerization and post-crosslinking reaction. The chemical and porous structures of these novel resins were characterized with BET, FT-IR and elementary analysis, respectively. The results showed that these novel adsorptive materials possessing abundant crosslinked networks had high specific surface areas (up to 1191.26 m2/g), large pore volumes (0.2-1.4 ml/g), narrow pore size distributions (mainly in the range of micropores and small mesopores). © Indian Academy of Sciences.
