Abstract:
The content of polyisobutylene in polyisobutylene succinic anhydride intermediate product was determined by high performance liquid chromatography with external standard method, and detected by differential detector. The self-made modified alumina column (4.6mm × 250mm,15.0 μm) was used as the column, and n-hexane was used as the mobile phase at a flow rate of 1 ml/min. The average linear range of polyisobutylene was 3.8-111g/L, the linear correlation coefficient was 0.9998, the relative standard deviation was 2.08%, and the recovery rate was 98.5%-101.5%. The method is simple, economical and accurate.
