Conditions

Temperature: 70 °C

Procedure

1.00 Part of 2,2'-azobis (2-methylpropanenitrile) is mixed with 764.5 parts of Latex #1 and heated to 70° C. while stirring under a nitrogen atmosphere. 50 Parts of a 50/50 solution of styrene and n-butyl methacrylate is added continuously with 227.3 parts of (RPS⃝) solution at 22.1 percent solids in water using the following schedule: 0 to 20 percent of monomers added over 2 1/2 hours at 70° C. and the remaining 80 percent monomers added with 0 to 100 percent of (RPS⃝) solution over 1 1/2 hours at 80° C. The reaction conditions are maintained for an additional 2 hours. The latex measures 32.8 percent solids, passes the acetone dilution, freeze-thaw stability and pesticide formulation freeze-thaw stability tests.
