実験手順

Incorporation of maleic anhydride into an emulsion aggregation particle at the bulk polymerization step. A stock solution of styrene (390 mL) and butylacrylate (110 ml) was prepared and to 400 ml was added TEMPO (3.12 g, 0.02 mole) and vazo 64 initiator (2.0 g, 0.0125 mole). This was heated under a nitrogen atmosphere to 135° C. (bath temperature) and then added to it dropwise a solution of maleic anhydride (9.8 g) in 100 mL of the styrene/butylacrylate stock solution that had been deoxygenated using nitrogen. The addition was done over a 30 minute period after which it was stirred for 5 more minutes and then cooled to afford a poly(styrene/maleic anhydride-styrene/butylacrylate) (Mn=4,990 with PD=1.23) solution in styrene/butylacrylate monomer.
