Abstract:

Polymethylmethacrylate-butylmethacrylate （PMMA-BMA） resin was prepared by means of microwave irradiation. The morphologies and textural properties of the product were then characterized using SEM. Moreover, the effects of monomer proportion, the initiator dosage, the dispersant dosage, the cross-linking agent dosage and the microwave power on the oil fume-adsorbing capacity of the resin were investigated. The results show that the adsorption ratio is up to 0. 191 at 60℃ when the mass ratio of MMA to BMA is 0.8：1 and when the dosages of the initiator, the dispersant and the cross-linking agent are respectively 0. 4%, 0. 3% and 0.35%. As compared with the traditional water-bath heating, microwave irradiation shortens the reaction time from 6 h to 2 h and results in a greater adsorption capacity even than those of the activated carbon and the commercial high-capacity G-1651 resin.
