Versuchsvorschrift

A styrene-butadiene-itaconic acid copolymer latex was prepared by adding to a pressure reactor with constant stirring 24.24 parts water, 0.5 parts itaconic acid, 0.8 parts of a 10 percent solution of Aerosol A-196 surfactant (sodium dicyclohexyl sulfosuccinate available from American Cyanamid Co., Wayne, New Jersey), and 0.5 parts of a polystyrene seed, 25 nm particle size. The mixture was heated to 150° F., and 0.2 parts sodium persulfate was added to initiate the reaction. Then 40 parts butadiene, 60 parts styrene, 1.0 part Sulfole 120 mercaptan, (tertiary dodecyl mercaptan available from Phillips Chemical Co., a subsidiary of Phillips Petroleum Co., Bartlesville, OK), dissolved in styrene, an additional 1.2 parts of 10 percent Aerosol A-196, 0.03 parts Versene 100 (sodium ethylene diamine tetraacetate available from Dow Chemical Co., Midland, MI), and 5 parts MAGME-100 (methyl acryloamidoglycolate methyl ether, available from American Cyanamid Co., Wayne, NJ) were added over a 6 hour period. The final mixture was heated at a temperature of 170° F. for 5 hours. The resulting emulsion polymer was cooled and removed from the reactor. It had a pH value of 2.3, which was adjusted to pH 7.0 with ammonium hydroxide. Total solids were 51 percent.
