Free radical post-crosslinked adsorbent and method of preparation

摘要

The present invention relates to a kind of radical post-crosslinking adsorbent and preparation method thereof, described radical post-crosslinking adsorbent comprises: polymerized unit (a) is at least a many vinyl aromatic monomers and at least a mono vinyl aromatics monomer that (b) is no more than 45wt% of 55wt% at least; And the suspension of 0.5-2.5mmol/g is two strong; Wherein, the scope of the BET specific area of the described adsorbent in dry back is 650-1000m ²/ g, the BET average pore size is 7.2-10nm, and the BET pore volume is 1.29-2.45mL/g, and BJH absorption micro pore volume accounts for below 20% of total BJH adsorption hole volume, and HK absorption micro pore volume accounts for below 21% of total BJH adsorption hole volume.
