摘要：
以三氧化硫脲(甲脒磺酸)、乙二胺和乙二酸为原料合成了胍羧缩聚阳离子聚电解质。该阳离子聚电解质在酸中稳定，在pH>10水溶液中快速降解;对水体中的微小颗粒和相对分子质量较大的阴离子具有优异的絮凝作用。在酸性介质中收集的絮体可以加碱使其中的阳离子聚电解质破坏，使絮凝回收的有用材料免遭絮凝剂污染而被重新利用。

Abstract:
The cation polyelectrolyte has been prepared by using aminoiminome than sulfonic acid,ethylenediamine and oxalic acid as materials.The cation polyelectrolyte is stable in acid aqueous and it is decomposed quickly in aqueousof pH10.It has excellent flocculating effect on particlesand bigger anions.If a right amount of base is added to the flocculent pulp,the polyelectrolyte in the pulpisde composed and the materials from the medium would not be polluted and may be re-utilized.
