Методика

An aqueous solution of DOWFAX surfactant (0.68 g) in 514 g of deionized water was heated to 76° C., and an initiator solution of 8.2 g of ammonium persulfate in 45 g of deionized water was added. A second aqueous solution of 10.8 g DOWFAX, 257 g deionized water was prepared, and a monomer solution of 467.1 g methyl methacrylate (MMA), 168.4 g butyl acrylate (BA), 30.9 g of β-carboxyethyl acrylate (β-CEA) and 7.5 mL dodecylthiol was added to form a monomer latex suspension. The monomer latex suspension is then added dropwise over the course of 3 hours into the first aqueous solution. Polymerization was continued for another 4 hours after completion of the addition. A poly(MMA/BA/β-CEA) polymer latex with a solids content of 45% was obtained.
