Abstract: A macroporous copolymer GET to be used as the matrix for expanded bed adsorption(EBA)was synthesized by suspension polymerization in the presence of porogenic agents from glycidyl methacrylate(GMA)and ethylene dimethacrylate (EDMA) with surface-modified superfine TiO₂ embedded.In this paper, the effects of the amount of TiO₂, the crosslinking degree, the amount of porogenic agent and their proportion on the copolymer wet true density and its porous structure，such as specific surface area, average pore diameter and pore volume were investigated.
