摘要：
Suspension copolymerization of styrene and divinylbenzene (DVB) was carried out using benzoyl peroxide as initiator and magnesium hydroxide as suspending agent in water at 80 degrees C under nitrogen atmosphere to produce styrene-DVB copolymer beads. These beads were characterized by infrared spectroscopy, thermal gravimetric analysis, and scanning electron microscopy. Porosity generated in styrene-DVB copolymer beads by incorporation of solvents in the polymerization system was confirmed by SEM micrograph, apparent density, swelling measurements, and Brunauer, Emmett, Teller surface area.
