Solution Property of Sulfonated Polystyrene Lanthanum Ionomers
Abstract:
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 same sulfonation degree exhibited higher reduced viscosity and intrinsic viscosity when the polarity of the solvents was high. The lower the sulfonation degree of SPS-La, the higher the reduced viscosity of SPS-La, especially in case of estremely dilute dolutions. The order of the reduced viscosity and the polyelectrolyte effect tendency are:SPS-Na > SPS-Zn > SPS > SPS-La.
