| Abstract: | A series of polyester ionomers with various cotents of sulfonate group are prepared from dimethyl terephalate (DMT) and dimethyl (sodiosulfo) phathalate (SIPM) by ester- exchange reaction and then melt co - polycondensation. The ionic groups in the polymers are qualitively and quatitively characterized by means of infra - red absorption spectrosco-py and flame atomic absorption spectrometry respectively. The influence of the ion contents on the intrinsic viscosities of the ionomers are investigated; the thema; and crystalline properties of the ionomers are studied by TGA, DSC, WAXS and polarizing light microscopy. |
