While polymer solution flows through the capillary of Ubbelohde viscometer,the adsorption of polymer molecules on the surface,sometimes,seriously changes the physical and chemical properties of the surface,especially when electrolyte is added into the solution.

當(dāng)聚合物溶液流過烏氏黏度計(jì)的毛細(xì)管時(shí),由于聚合物分子在毛細(xì)管表面吸附,該表面的物理和化學(xué)性質(zhì)將發(fā)生很大的改變,尤其是當(dāng)溶液中含有大量的電解質(zhì)時(shí)這種情況更為突出。
