二甲基二烯丙基氯化铵—丙烯酰胺共聚物的研究

Study on Polydimethyldiallylammonium Chloride-acrylic Amide

在分子设计的基础上 ,采用补加活泼单体法制得二甲基二烯丙基氯化铵—丙烯酰胺共聚物 ,其特性粘度[η]=2 .76 ,阳离子度 =2 3.8% .絮凝实验证明 ,该聚合物作为絮凝剂特别适用于高浊度水的处理 ,当与聚合硫酸铁复配使用时 ,效果更为理想 .

On the basis of molecule design, polydimethyldiallylammonium chloride-acrylic amide was obtained by the reaction in which more active monomer was supplemented in batches. The intrinsic viscosity of the polymer[η]=2.76 and the cation content of polymer =27%. Jar test proved that the polymer is especially suitable as a flocculant for the water which has high turbidity. When it is used along with PFS as a coagulant for water treatment, the flocculation efficiency is very satisfactory.
