Polyisobutylene plays a significant role as the long oil-soluble tail that can produce excellent oil solubility and prevent the engine's aggregation of deposit particles. We have demonstrated an easy work-up synthesis of pentaethylenehexamine-terminated polyisobutylene (PIB-PEHA) using BF3 as a co-initiator. Fourier transform-infrared (FT-IR) spectroscopy, UV-vis spectrophotometer, thermogravimetric analysis and liquid chromatography-electrospray ionization-quadrupole time-of-flight-tandem mass spectrometry (LC–ESI-QTOF-MS/MS) were performed to analyze the chemical properties of the prepared product. The results showed that a reaction time of 4 h and co-initiator loading of 0.023 M is the best condition for synthesizing PIB-PEHA. This study shows that the methodology has potential for industrial application as an alternative option to manufacture dispersants with economic benefits.
