摘要：

Styrene-divinylbenzene copolymers were synthesized by suspension polymerization in the presence of bis-2-diethylhexylphosphoric acid (DEHPA) and methyl ethyl ketone (MEK) as diluents for the monomers. The influence of DEHPA/MEK ratio and dilution degree on the formation of porous structure of the copolymers was investigated by surface area, pore volume, pore size distribution and apparent density. It was found that 50% DEHPA in the diluent mixture always leads to macroporous sorbents whatever the MEK content.
