Synthesis, Aggregation Behavior and Emulsification Characteristic of a Multi-sticker Amphiphilic Polymer

A multi-sticker amphiphilic polymer P(AM-NaA-DCHAM) was synthesized using micellar polymerization. Fluorescent spectroscopy, rheology and SEM were used to characterize the aggregation behavior of P(AM-NaA-DCHAM) solutions. Above CAC, aggregation formed by intermolecular association of hydrophobic groups can induce large quantities of hydrophobic microdomains and strong elastic polymer gel network structures in P(AM-NaA-DCHAM) solutions. O/W crude oil emulsions stabilized by P(AM-NaA-DCHAM) were prepared, and a laser particle size analyzer and Turbiscan lab stability analyzer were employed to study their stability. O/W crude oil emulsions stabilized by P(AM-NaA-DCHAM) get more stable as polymer concentration increases. The stability mechanism of O/W crude oil emulsions stabilized by P(AM-NaA-DCHAM) is probably because the elastic polymer gel structure of P(AM-NaA-DCHAM) in the continuous phase has the ability to hold oil droplets.
