Abstract:

The photosensitive amphiphilic copolymer poly-(styrene-alt-maleic anhydride)-co-poly (7-(4-vinylbenzyloxyl)-4-methylcoumarin-alt-maleic anhydride) (PSMVM) micelles with various degrees of swelling were used as polymeric micellar emulsifiers to stabilize toluene-in-water emulsions. This paper focuses on the influence of the degree of photo-crosslinking on the micellar structure and the emulsification performance of the micelles. The research results indicated that the degree of photo-crosslinking, the degree of swelling, and the charge on the micelles played an important role in the micellar structure and the emulsifying performance of the micelles.

Key words: Amphipathy, Self-assembly, Photo-crosslinking degree, Swelling degree, Emulsification
