example 1
[0152] Polymers are synthesized in staged semi-batch emulsion polymerization to produce staged gradient latex polymer particles. 168.6 g of EA, 200 g of MAA, 1.36 g of TMPTA, and an additional 26.2 g of deionized water were added under a nitrogen atmosphere to a first reactor equipped with a stirrer containing 146.72 g of deionized (D.I.) water, 10 g of ethoxylated fatty alcohol emulsifier and 10.67 g of sodium lauryl sulfate (30% active (wt. / wt.) in water) were mixed at 900 rpm to form a stable monomer emulsion. 913.84 g of deionized water and 1.27 g of sodium lauryl sulfate (30% active (wt. / wt.) in water) were added to a second reactor equipped with a stirrer and mixed at 210 rpm under a nitrogen atmosphere while heating. When the contents of the second reactor reached a temperature of 84°C, 10 g of ammonium persulfate solution (1.6% aqueous solution by weight (wt. / wt.)) was injected into the heated surfactant solution. The monomer mixture from the first reactor was gradua...
example 2-16
[0155] The polymers of Examples 2 to 16 were polymerized using the same components and conditions as for the preparation of the polymer described in Example 1, except that the amounts of the respective monomers were changed as set forth in Table 1 . The MFFT values for each of the synthetic polymers and commercially available rheology-modified polymers were determined by the test methodology described above. MFFT results are reported in Table 2.
example 17
[0157] The polymer synthesized in this example was polymerized using the same components and conditions as the preparation of the polymer described in Example 1, except for how the secondary monomer mixture was added. The second stage monomer mixture was added in multiple batches (3 times at 50 minute intervals). After completion of the monomer addition, the reaction mixture was maintained at a temperature of 88°C for 150 minutes. The resulting polymer emulsion product was cooled to room temperature, drained from the reactor and recovered. The MFFT of the polymers was measured and reported in Table 2.
[0158] The monomer amounts reported in Table 1 are the total amount of monomer components used to prepare the polymers. The monomer amounts reported in Table 1A are the amounts of each stage used to make the polymers.
