Abstract

Zinc sulfonated SBR prepared by the sulfonation of styrene units in SBR, followed by the neutralization of the resultant SBR sulfonic acids, behaves as ionic thermoplastic elastomer, and shows improved physical properties compared to SBR. Studies include X-ray fluorescence analyses (XRF), FTIR spectroscopy, dynamic mechanical analyses (DMA) and measurement of physical properties.
