| Abstract: | In order to solve the problems existing in the synthesis of poly(maleic anhydride-acrylamide) in organic solvents,such as low content,low utilization rate of maleic anhydride and low yield of the copolymer,radical precipitation polymerization of acrylamide with maleic anhydride in tetrahydrofuran(THF) was used to synthesize MA-AAM.The effects of monomer molar ratio,concentration of monomers,amount of initiator and reaction time on copolymerization reaction were investigated.Maleic anhydride(MA) monomer content was obtained by chemical calculation through acrylamide(AAM) content measured by Kjeldahl method.The content,the utilization rate of maleic anhydride and the copolymer yield were improved to 42%,95% and 61% respectively by recycling the polymerization residue eight times.The chemical structure of the copolymer was analyzed by Fourier transform infrared spectrum(FT-IR) and the relative molecular weight(M-n=1.36×104,M-w=1.94×104,D=1.4) of the copolymer was measured by gel permeation in chromatography(GPC). |
