【摘要】 <正> 纤维素硫酸半酯钠盐是一种阴离子型强聚电解质,共水溶液是典型的聚电解质溶液。本文以粘度法研究了多种外加盐对纤维素硫酸半酯钠盐溶液粘度的影响,考察了外加盐浓度、外加盐阳离子和阴离子与大分子形态结构的关系,对高价Al⁺³离子的桥架效应也作了初步探讨。更多还原

【Abstract】 The influences of a variety of external salts on the solution viscosity of sodium-cellulose sulfate half-ester were studied by viscometry method. The dependences of polymer conformation structure on salt concentration and cation as well as anion of salt were discussed seperately. The influences of polyvalent cation was also discussed simply.更多还原
