本文采用乌氏粘度计研究了聚合物浓度和温度对纤维素硫酸半酯钠盐溶液粘度的影响,分别考察了Arrhenius公式(η=A′e~(E/RT))中表观流动活化能E和指前项A′与溶剂性质,聚合物浓度以及大分子形态等因素的关系,对于溶液特性粘度随温度的变化也作了初步的探索。
In this paper, Ubbelohde viscometer was used to study the effect of polymer concentration and temperature on the viscosity of cellulose sulfate half ester sodium salt solution. The activation energy of apparent flow in Arrhenius formula (η = A’e ~ (E / RT) E and Pre-term A ’with the solvent properties, polymer concentration and macromolecular morphology and other factors, for the solution viscosity has also made preliminary changes with temperature.
