二烯丙基二甲基氯化铵—丙烯酰胺反相乳液聚合的动力学特征研究

STUDIES ON KINETICS OF INVERSE EMULSION COPOLYMERIZATION OF DIALLYLDIMETHYL AMMONIUM CHLORIDE AND ACRYLAMIDE

采用油酸失水山梨醇酯（ＳＰＡＮ）－壬基酚聚氧化乙烯醚（ＯＰ）复合乳化剂与Ｋ２Ｓ２Ｏ８－Ｎａ２ＳＯ３氧化还原引发剂，进行二烯丙基二甲基氯化铵－丙烯酰胺反相乳液共聚合，测得单体的竞聚率为γＤＡＤＭＡＣ＝０．１４±０．１１，γＡＭ＝５．０５±０．６６；在单体浓度为２５─４５％，引发剂浓度０．０６—０．１％，乳化剂浓度为５—９％，聚合温度３０３Ｋ条件下，得到了共聚反应动力学方程：Ｒｐ＝ｋ［Ｍ］０．６８［Ｉ］１．３１［Ｅ］０．７３，文中对上述结果做了解释．

sing SPAN-OP composite emulsifier and K2S2O8-Na2SO3 redox initiator, the inverse emulsion copolymerization of diallyldimethyl ammoniumchloride (DADMAC) and acrylamide (AM) was developed. The monomer reactivity ratios are γDADMAC=0.14±0.11,γAM=5.05±0.66; Under the conditions of total concentration of monomer being 25-45%, initiator concentration being 0.06-0.1%, emulsifier concentration being 5-9% and polymerization temperature being 303K, the kinetic equation of copolymerization can be expressed: Rp=k[M]0.68[I]1.31[E]0.73.In this paper, above results are explained.
