摘要

In the presence of Friedel-Crafts catalyst

the chloromethylated copolymer of styrene-divinylben-zene may react with each other and cross-link by itself Thus a new type of polymeric adsorbent wasobtained

and its structure was identified by its physical properties and infrared spectra. The Friedel-Crafts reaction is manifestly affected by the nature of the solvent

the kind and amount of catalystused

reaction temperature and reaction time

etc. The porous structure and physical properties of the adsorbent prepared have been investigated systematically.The adsorbent has ligh specific surface area(1000-1300 m2/g)

porosity

narrow pore distribution

high skeleton density and good mechanical properties.
