【Abstract】 Styrene(St),maleic anhydride(MA)and crylonitril(AN),initiated by dibenzoyl peroxide(BPO)in toluene,were copolymerized to get terpolymer(SMAN)according to the theory of free radical copolymerization,then SMAN was esterificated with hexadecanol,octadecanol or compound of two to get the product(SMANE).Through orthogonal test,monomer molar proportion,the amount of initiator,concentration of monomer,temperature,time and ratio of acrylonitril were studied.Fourier transform infrared spectrum,differential thermal analysis and polarization microscope were used to characterize polymer and to study mechanism of paraffin inhibition.更多还原
