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 m~2/g and large pore volumes range from 0.5 to 1.2 cm~3/g.
