摘要
对苯二甲酸二甲酯（ＤＭＴ）．３．５－间苯二甲酸二甲酯苯磺酸钠（ＳＩＰＭ）通过与乙二醇的酯交换及熔融共缩聚反应，得到了一组不同离于含量的离聚物。考察了产物中离子含量对其特性粘数的影响；并利用ＤＳＣ、ＴＧＡ、ＷＡＸＳ等实验手段对产物的热性质、结晶性等进行了研究。
A class of polyester ionomers with various contents of sulfonate group were prepared from dimethyl terephalate(DMT)and dimthyl(sodiosulfo)phathalate (SIPM) by ester-exchange reaction and then melt co-polycondensation.The influence of the ion contents on the inherent viscosities of the ionomers were investigated; the thermal and crystalline properties of the ionomers were studied by TGA. DSC and WAXS experimental methods.
