中文摘要：

利用稀溶液粘度法对所合成的水溶性共轭聚合物PPEAS03的分子量进行了估测．先通过含0．1MNaN03的PPEAS03水溶液的粘度测量数据求出其特性粘数[η]，再利用Mark—Houwink方程[η]=KMηα和有关文献中的三种参考聚合物的K、a值计算得到聚合物的粘均分子量Mη，最后取其平均值得到PPEAS03的粘均分子量为Mη≈150KD．

英文摘要：

In this paper, molecular weight of the water-soluble conjugated polymer PPEASO3 was estimated by means of viscosity method of dilute solution. The experimentally obtained value of [η] for PPEASO3 in 0.1M NaNO3 aqueous solution has been used to compute the polymer, s Mη value by use of the Mark-Houwink relation （[ η] = KMηa） and the values of K and a obtained from the literature for three different reference polyelectrolytes. The mean value of the calculation results suggest that for this polymer viscosity average molecular weight Mη≈150KD.
