Polyisobutylene succinic anhydride,N,N- dimethyl- 1,3- propylene amide and 3- chloro- 1,2-propylene glycol were used as the main raw materials to synthesis cationic quaternary ammonium salt based on polyisobutylene succinic imide by imide reaction and quaternary ammonium,the structure of the product was characterized by infrared spectroscopy. The limit emulsifying properties and storage stability of the product were determined,the results showed that the emulsification stability of the product was better. The limit emulsifying properties and the storage stability of the produce were superior to polyisobutylene succinimide（ T152） and suitable for emulsification explosives industries,so the synthetic produce had good prospects for promotion.
