Facile synthesis of hypercrosslinked resin via photochlorination of p-xylene and succedent alkylation polymerization

A combination of photochlorination of p-xylene and succedent Friedel–Crafts alkylation polymerization was firstly used in the preparation of the hypercrosslinked adsorptive resin. The data of GC–MS and GC showed that a series of chlorizates were produced when p-xylene was photochlorinated. Hypercrosslinked resins could be synthesized by copolymerization, self-polymerization of chlorizates or post crosslinking reaction. The chemical structure and micromorphology of the porous resins were characterized by BET, FT-IR, SEM and elementary analysis (EA). The results showed that the novel adsorptive resins possess high BET surface near to 1038 m2/g and large pore volumes range from 0.5 to 1.2 cm3/g.
