| Abstract: | 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=kM]0.68I]1.31E]0.73.In this paper, above results are explained. |
