The results show that when molar ratio of epichlorohydrin and dimethylamine is set as 1.5:1 and the amount of 1,2-diaminoethane is 3%, polyamine flocculants get the best viscosity and cationic degree and have excellent decoloration efficiency through the adsorption and subsequent formation of particle-polymer-particle bridges.

结果表明，环氧氯丙烷和二甲胺的摩尔比为1.5：1，乙二胺加入量为3%时，聚合物的粘度和阳离子度最大，具有较强的吸附架桥和电中和作用，对染料废水有较好的脱色效果。

The influences of the amount of triethylenetetramine, temperature, molar ratio of epichlorohydrin and dimethylamine, and reaction time on the viscosity and cationic degree of the polyamine flocculants were investigated. Then the influence of pH value, flo-cculant dosage and temperature on flocculation effect were studied.
