Preparation and Characterization of Oil Sorbents from Grafting Polymerization with MMA and Cellulose of Solidago canadensis

With Methacrylate (MMA/BMA) as monomer, benzoyl peroxide (BPO) as initiator and cetyl trimethyl ammonium bromide (CTAB) as cross linker, high oil sorbents of modified Solidago canadensis were synthesized by suspension graft copolymerization. The effects of the ratio of Methl Methacrylate (MMA) to n-butyl methacrylate (BMA), the amount of initiator and cross linker were investigated. The best reaction condition was obtained when the ratio of MMA to BMA was 0.75:1, mass fractions of BPO, CTAB were 0.7%, 1.2% respectively, and maximal oil absorbency is 21.036 g/g. In addition, the oil absorptive abilities on water surface of four kinds of resin were discussing. Moreover, structure and properties of resins were studied by means of SEM.
