実験手順

Deionized water (600 g), a monomer mixture composed of 438.8 g of a vinyl chloride monomer (97.5% by weight based on total charge monomer amount), 11.2 g of vinyl acetate (2.5% by weight based on total monomer charge amount), and 2.25 g of potassium persulfate were charged into a 2.5-L autoclave. The reaction mixture was stirred with a stirring blade while maintaining the rotation speed at 120 rpm, and the temperature of the reaction mixture was raised to 60° C. to start a polymerization. A 5% (by weight) aqueous solution of sodium dodecylbenzenesulfonate (180 g, 2% by weight based on total monomer charge amount) was continuously added from the start of the polymerization to 4 hr after the start of the polymerization, and the polymerization was stopped when the polymerization pressure was dropped by 0.6 MPa from a saturated vapor pressure of the vinyl chloride monomer at 60° C. Thereafter, the residual monomer was recovered to obtain a vinyl chloride-vinyl acetate emulsion.
