Comparison of alkenyl succinic anhydride emulsions stabilized by laponite modified with ethylamine, diethylamine and triethylamine

The modifications of laponite particles with three short amines, that is, ethylamine, diethylamine and triethylamine, were compared and the amine-modified laponites were used to stabilize alkenyl succinic anhydride emulsions. The results show that the emulsion stability can be improved while the emulsion droplet size can be reduced by using the amines to modify laponite particles. Among the three amines, the diethylamine exerts the largest while the triethylamine exerts the smallest effects on the zeta potential of laponite, the turbidity of laponite aqueous dispersion and the emulsion stability and morphology. The emulsion with the smallest droplet size shows the highest sizing performance.
