摘要
A post-crosslinked adsorbent comprises: monomer units of (a) at least 55 wt% at least one polyvinylaromatic monomer and (b) up to 45 wt% at least one monovinylaromatic monomer; and 0.5-2.5 mmol/g pendent vinyl groups; wherein the dry adsorbent has BET specific surface area in the range of about 650-1000 m2/g, BET average pore diameter 7.2-10 nm, BET porosity 1.29-2.45 mL/g, BJH adsorption micropore volume was less than 20% of total BJH adsorption pore volume, and HK micropore volume was less than 21% of total BJH adsorption pore volume. The invention is also directed to a preparation method for the polymeric adsorbent.
