The relationship between the reduced viscosity and concentation of sulfonated styrene-isoprene- styrene triblock copolymer(SSIS) and its ionomers in toluene and toluene/methanol solutions were studied. The intrinsic...
The viscosity behavior of the sulfonated polystyrene lanthanum ionomers(SPS La) has been investigated in comparison with the sodium and zinc ionomers in polar solvents. The results indicated that the SPS La with the s...
