| 摘 要： | 用恒定外加盐浓度稀释法,测定了辐射合成的线型聚丙烯酸钠在含不同浓度的硝酸钠溶液中以及分别添加不同种类的外加盐时的粘性行为。结果表明:聚丙烯酸钠溶液的比浓粘度η_(sp)/C与溶液浓度C随外加盐浓度的升高而降低。当外加盐浓度在一定范围内变化时,用直线外推法求得的特性粘数趋于一致。当添加不同种类外加盐时,由于其电离度的差异,对聚丙烯酸钠水解的抑制或消除作用有所不同,从而使外推得到的特性粘数也不相同。

| Abstract: | This paper presents the effects of dose rate and concentration of the monomer on the conversion rateand molecular weight of polymer in irradiated polymerization. The intrinsic viscosity of sodium polyacrylate in different concentration of NaNO3 and other added salts has been determined experimentally by the method of dilution in constant concentration of added salts. |
