We synthesized a series of polar
hyper-cross-linked resins, and
the porosity and polarity of these resins were effectively tuned by
feeding different amounts of glycidyl methacrylate (GMA). As the feeding
amount of GMA increased, the Brunauer–Emmett–Teller
surface area, pore volume, micropore area, and micropore volume sharply
decreased; the pore size distribution of the resins showed a large
population of pores in the microporous region extending to a higher
part of the mesoporous region, and the O content increased while the
static contact angle lowered. The adsorption experiments indicated
that these resins were efficient for adsorption of 2-naphthol and
4-hydroxybenzoic acid (4-HBA). The adsorption process was very fast,
and the kinetic data for the adsorption of 2-naphthol could be well-fitted
by a pseudo-second-order rate equation, while those for the adsorption
of 4-HBA could be characterized by a pseudo-first-order rate equation
