摘要
利用稀溶液粘度法对所合成的水溶性共轭聚合物PPEASO3的分子量进行了估测.先通过含0.1M NaNO3的PPEASO3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]=KMαη和有关文献中的三种参考聚合物的K、α值计算得到聚合物的粘均分子量Mη,最后取其平均值得到PPEASO3的粘均分子量为Mη≈150KD.
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.
