YANG Kai-ji1,2,SU Wen-qiang1,XU Qing-lin2,WANG Ke-ming2(1.Key Laboratory of bio-based Material Science and Technology of Ministry of Education, Northeast Forestry University,Harbin 150040,China;2.Research Institute of Beijing Hengju Chemical Group Corporation Beijing 101109,China)  
In this paper,first of all,ternary phase diagram of complex emulsifier,monomer solution and cyclohexane was mapped through conductivity method and visual method.Then dynamics research was carried out by analysis of reaction temperature,concentration of monomer,initiator dosage and emulsifier dosage on polymerization rate and relative molecular weight of PDADMAC/AM/AA(PDAA),by which apparent activation energy of polymerization reaction was determined,which was 9.84 kJ/mol.Dynamics relationship for polymerization rate and relative molecular weight were obtained also,which were R p∝[M]1.05[E]0.21[I]0.35 and M v∝[M]1.18[E]-1.16[I]-0.24.Finally,through a scanning electron microscope particle morphology of PDAA reverse micro-emulsion and PDAA solution were observed.
