반응 단계

100 g of 25 wt % polyacrylic acid aqueous solution and 2.5 g of N-carboxy methyl acrylamide were polymerized at 60° C. for 3 hours for partial crosslinking. Potassium hydroxide was added to neutralize the pH value to 7.0 and 40 g of T-P400(polymer of triol and propylene oxide, Union Carbide Co., U.S.A.) and 1 g of sodium 2-pyrrolidone-5-carboxylate were added. Deionized water was then added to the resultant product to adjust the solid content thereof to 35 wt %. The viscosity of the resultant solution was measured as 5500 to 6000 cps(30° C.). The resulting product was tested according to the procedures set forth in Example 1, and the test results are listed in Table 1.
