COMPARATIVE ANALYTICAL STUDY OF POLYISOBUTYLENE SUCCINIC ANHYDRIDE-MODIFIED TRIETHANOLAMINE EMULSIFIER

Abstract

An analytical comparative study was performed between the prepared emulsifiers polyisobutylene succinic anhydride (PIBSA) and the commercial LZ2735 and LZ2745 materials. The PIBSA-1,-2 and PIBSA/TEA were prepared by reacting the reactive polyisobutene (PIB) with maleic anhydride via isothermal heating at 250°C for 10 h. Then, PIBSA was heated with triethanolamine at 80°C for 2 h to give PIBSA/TEA.
