Versuchsvorschrift

A 2.5-L autoclave was charged with 900 g of deionized water, 750 g of vinyl chloride monomer, 5 g of 3 wt % potassium persulfate, and 75 g of an aqueous sodium dodecylbenzenesulfonate solution having a concentration of 5 wt % (0.50 parts by weight based on the monomer), and by raising the temperature to 66° C., emulsion polymerization was allowed to proceed. After the saturated vapor pressure of vinyl chloride at 66° C. was reduced to 0.7 MPa, unreacted vinyl chloride monomer was recovered. To the residue, 235 g of an aqueous sodium dodecylbenzenesulfonate solution having a concentration of 5 wt % (1.57 parts by weight based on the monomer) and 45 g of an aqueous potassium laurate solution having a concentration of 5 wt % (0.30 parts by weight based on the monomer) were additionally added to obtain a vinyl chloride resin latex (amounts of sodium dodecylbenzenesulfonate and potassium laurate, per 100 parts by weight of vinyl chloride homopolymer: 2.30 parts by weight and 0.33 part by weight, respectively). The average particle diameter was measured and found to be 0.1 μm.
