Abstract
Styrene-divinylbenzene copolymers were synthesized by suspension polym erization in the presence of bis-2-diethylhexylphosphoric acid (DEHPA) and methyl ethyl ketone (MEK) as diluents for the monomers. The influ ence of DEHPA/MEK ratio and dilution degree on the formation of porous structure of the copolymers was investigated by surface area, pore vo lume, pore size distribution and apparent density. It was found that 5 0% DEHPA in the diluent mixture always leads to macroporous sorbents w hatever the MEK content.
