聚乙烯醇硫酸钾（PVSK）的制备及其结构分析

PREPARATION AND IDENTIFICAION OF POLY (VINYL ALCOHOL POTASSIUM SULFATE)

研制了胶体滴定法所需的标准阴离子型聚电解质试剂ＰＶＳＫ，探讨了合成条件的影响，并对ＰＶＳＫ的结构进行了分析。为阳离子聚电解质测试中应用胶体滴定法提供了物质条件。

A standardized anionic polyelectrolyte,poly(vinyl alcohol potassium sulfate)(PVSK)used in the colloidal titration,was prepared. Some effects in the preparation were discussed. The structure of PVSK was identified.The work provided the material condition with the improvement and use of the colloidal titration in the determination of cationic polyelectrolytes. PVSK is a valuable reference substance.
