Embodiment 1
[0076] The reactor was charged with 2,831.38 g water, 42.2 g AEROSOL A102 (sulfosuccinate, Cytec) (31% solution), 9.53 g TERGITOL 15S5 (ethoxylated alcohol, Union Carbide), 45.47 g TERGITOL 15S40 ( Ethoxylated alcohol, UnionCarbide), (70% solution), 81.67g sodium ethylene sulfonate (25% solution), 10.89g ferric sulfate hexahydrate (1% solution), 10.89g VERSENE (tetrasodium ethylenediaminetetraacetate , Dow Chemical), 1.09 g sodium formaldehyde sulfoxylate, 0.35 g sodium acetate and 108.9 g vinyl acetate. The pH of the starting charge (without vinyl acetate) was adjusted to pH 4 with phosphoric acid. The reactor was then flushed with nitrogen and then ethylene and heated to 50°C with stirring, then pressurized to 800 psi ethylene. At an addition rate of 2 hours, the addition of tert-butyl hydroperoxide solution (395.18 g water and 81.65 g tert-butyl hydroperoxide) and buffered sodium formaldehyde sulfoxylate solution (396.75 g water, 73.02 g formaldehyde sulfoxylate) was start...
Embodiment 2
[0083] The reactor was charged with 2,896.04g water, 12.59g AEROSOL A102 (31% solution), 3.02g TERGITOL 15S5, 14.35g TERGITOL 15S40 (70% solution), 75.55g sodium ethylene sulfonate (25% solution), 10.07g six Ferric sulfate hydrate (1% solution), 10.07g VERSENE, 1.01g sodium formaldehyde sulfoxylate, 0.33g sodium acetate and 100.73g vinyl acetate. The pH of the starting charge (without vinyl acetate) was adjusted to pH 4 with phosphoric acid. The reactor was then purged with nitrogen and ethylene and stirred to 50°C, then pressurized to 800 psi ethylene. At an addition rate of 2 hours, the addition of tert-butyl hydroperoxide solution (337.97 g water and 69.83 g tert-butyl hydroperoxide) and buffered sodium formaldehyde sulfoxylate solution (337.97 g water, 69.18 g formaldehyde sulfoxylate) was started. sodium sulfate and 2.94 g sodium acetate). When the temperature rise indicated initiation, the jacket temperature was increased to 70° C., and the emulsified monomer mixture w...
Embodiment 3
[0089] The reactor was charged with 2,896.04 water, 8.81 g AEROSOL A102 (31% solution), 2.01 g TERGITOL 15S5, 9.57 g TERGITOL 15S40 (70% solution), 75.55 g sodium ethylene sulfonate (25% solution), 10.07 g sulfuric acid hexahydrate Iron (1% solution), 10.07g VERSENE, 1.01g sodium formaldehyde sulfoxylate, 0.33g sodium acetate and 100.73g vinyl acetate. The pH of the starting charge (without vinyl acetate) was adjusted to pH 4 with phosphoric acid. The reactor was then purged with nitrogen and ethylene and heated to 50°C with stirring, then pressurized to 800 psi ethylene. At an addition rate of 2 hours, the addition of tert-butyl hydroperoxide solution (323.46 g water and 66.83 g tert-butyl hydroperoxide) and buffered sodium formaldehyde sulfoxylate solution (323.46 g water, 59.52 g formaldehyde sulfoxylate) was started. sodium sulfate and 2.94 g sodium acetate). When the temperature rise indicated initiation, the jacket temperature was increased to 70° C., and the emulsifie...
