高分子量阳离子聚丙烯酰胺共聚物P(DMDAAC-AM)的合成

Synthesis of High Molecular Weight P(DMDAAC-AM)

用复合引发体系(K2S2O8-NaHSO3-AAP.2HCl)引发二甲基二烯丙基氯化铵与丙烯酰胺的水溶液共聚合,制得了特性粘数高于11 dL.g-1的阳离子聚丙烯酰胺共聚物PDA,探讨了助剂和引发剂的用量及单体配比对聚合物分子量的影响。

This paper introduced the copolymer of dimethyldiallylammonium chloride（DMDAAC） and acrylamide（AM）, whose intrinsic viscosity was over 11 dL·g^-1, was synthesised using multi-initiating system in aqueous solution. The effects of aids agent amount, initiator amount and monomer ratio on the molecular weight of copolymer were also discussed.
