| Abstract: | A new polyether quaternary ammonium salt(PECH-NNDMA) was synthesized using polyepichlorohydrin(PECH) as the raw material, N, N-dimethylaniline as the quaternary ammonium reagent. The influence of reaction time, reaction temperature and reactant mixture ratio on the grafting ratio of PECH was investigated. The structure of the PECH-NNDMA was characterized by infrared spectroscopy(IR) and element analysis(EA). The optimal process conditions are as follows: the reaction time is 7h, the reaction temperature is 70℃, n(PECH):n(NNDMA)=1:5. |
