Polystyrene-butadiene random copolymer with medium and low vinyl contents were synthesized via anionic polymerization with or without polar additives (TMEDA). The phenyl functionalized polystyrene-butadiene random copolymer with various phenyl contents were synthesized from polystyrene-butadiene random copolymer with medium and low vinyl contents via thiol-ene reaction. The phenyl functionalized polystyrene-butadiene random copolymer were sulfonated by the addition of 95% H2SO4 and acetic anhydride at R.T. in diethyl chloride. The sample films of sulfonated polymer PSB7-T-S with 8mol% to 15mol% sulfonation degree were checked by conductivity test, and the area resistances. The sulfonated phenyl functionalized PSB7-T-S15 could be used as the great ion-exchange resin with low Area resistance(less than 10 Ω·cm2), low water uptake(less than 20%) and higher ion-exchange capacity(general value: 0.4~2.6 meg/g). |
