Two approaches were used to synthesize two resins with different pore structures. In one way, the [sbnd]CH2Cl groups in macroporous chloromethylated polystyrene resin were transformed to methylene bridges, and achieved a hypercrosslinked resin with plentiful micropores (denoted GQ-06). In the other way, 50% of the [sbnd]CH2Cl groups in chloromethylated polystyrene resin was used to produce micropores, while the residual 50% of the [sbnd]CH2Cl groups was reacted with 2-aminopyridine, and prepared another resin with double pore structure of hypercrosslinked resin and macroporous resin (denoted G...
