Suspension and dispersion polymerization were chosen for their preparation. Dispersion copolymerization of styrene and divinylbenzene (DVB) in ethanol was stabilized by (hydroxypropyl)cellulose (HPC) and initiated with dibenzoyl peroxide . Monodisperse 1.4-µm microspheres were prepared in the presence of 3.6 wt% HPC. Microspheres were chloromethylated with chloromethyl methyl ether , chloromethyl ethyl ether or chloromethyl octyl ether to investigate the effect of the chloromethylation agent on the specific surface area of microspheres. Chloromethylated microspheres were hypercrosslinked in 1,2-dichloroethane (DCE) with SnCl4. The effects of the (DVB) and DCE/microsphere ratio on properties of the product were studied. Characterization of porous structure were done by dynamic desorption of nitrogen, cyclohexane regain and mercury porosimetry.
