A series of emulsion polymerizations of dibromostyrene (DBS)/2-ethylhexyl acrylate (2-EHA) were carried out in 8 oz. bottles. All the ingredients (122.50 or 180 parts by weight deionized water, 3 parts sodium dodecyl sulfate, 0.3 parts potassium persulfate, 0.2 parts t-dodecyl mercaptan and 100 parts total monomers in the ratio desired in the polymer) were charged into 8 oz. bottles and flushes well with nitrogen, and then reacted at 50° C. to about 45.8 or 36.5% solids in 15 hr. The whole bottle was cooled to room temperature and 3 parts deionized water and 0.18 parts 50% H2O2 added, followed by agitation for 20 minutes. The results of these preparations are set forth in Table I. The latices in Examples 1 and 2 perform well in a variety of coating applications, and display improved flame retardancy, while the latices in Examples 3 through 5 give very soft and tacky coatings.
