实验过程

As monomers, 123.75 g of styrene, 123.75 g of butyl acrylate, and 2.5 g of acrylic acid were used and mixed with 5.0 g of the emulsifier of the present invention product or the comparative product shown in Table 1 and 105 g of ion-exchanged water by using a homomixer, thereby preparing a mixed monomer emulsion. Aside from this, in a reactor equipped with a stirrer, a reflux condenser, a thermometer, a nitrogen inlet tube, and a dropping funnel, 122 g of ion-exchanged water and 0.25 g of sodium hydrogen carbonate were charged. A 36 g portion of the previously prepared mixed monomer emulsion described above was charged in the dropping funnel and added to the reactor all together, and then, the temperature was increased to 80° C. Thereafter, stirring was continued for 15 minutes. Subsequently, 0.5 g of ammonium persulfate as a polymerization initiator was dissolved in 20 g of ion-exchanged water, and the resulting solution was added to the reactor to initiate polymerization. Subsequently, 15 minutes after adding the polymerization initiator, 324 g of the rest of the mixed monomer emulsion was added dropwise thereto over 3 hours to carry out polymerization. Further, after maturation was allowed to proceed for consecutive 2 hours, the resultant was cooled and adjusted at a pH of 8 with ammonia water, whereby a polymer dispersion to be used for the evaluation experiments of the present invention was obtained.
