Abstract： |
| In this paper, terpolymers of 1-(Chloromethyl)-4-Ethenylbenzene (VBC) , butyl acrylate (BA) and Styrene (St) were synthesized with sodium dodecyl Sulfate (SDS) and octylphenol polyoxyethylene ether (OP-10) as multiple emulsifiers, water soluble ammonium persulfate (APS) as the initiator. Novel alkaline anion-exchange membranes were followed by quaternization and alkalization. The chemical structure of AAEM was confirmed by Fourier transform infrared spectrometry (FT-IR) , the thermal stability was investigated by thermal gravity analysis (TGA) , and the property of AAEM, including ionic conductivity, ionic exchange capacity, water uptake, chemical stability were characterized in this study. The results showed that the conductivity of AAEMcan reach at 3.824mS/cm at indoor temperature, theion exchange capacity is 0.5144 mmol/g, the water uptake is 22.79%.Andthe degradation time in 6M KOH is twenty days at indoor temperature.The prepared AAEM also possesses relatively high thermal stability and solvent resistance. |
