Description

得られた比較吸水性樹脂（２）１００質量部に１，４−ブタンジオール０．３８質量部、プロピレングリコール０．６３質量部、純水２．７４質量部の混合液からなる表面架橋剤を均一に混合した後、混合物を２１２℃で加熱処理した。混合物の加熱時間を３０分、４０分、４５分としたものをそれぞれ作製した。その後、得られた粒子をそれぞれ目開き７１０μｍのＪＩＳ標準篩を通過するまで解砕した。次に、解砕された粒子にペイントシェーカーテスト１を行った。こうして、表面が架橋された比較吸水性樹脂を得た。加熱時間３０分のものを比較吸水性樹脂（２−３０）、加熱時間４０分のものを比較吸水性樹脂（２−４０）、加熱時間４５分のものを比較吸水性樹脂（２−４５）とした。
得られた比較吸水性樹脂（３）１００質量部に１，４−ブタンジオール０．３８質量部、プロピレングリコール０．６３質量部、純水３．３９質量部、過硫酸ナトリウム０．１質量部の混合液からなる表面架橋剤を均一に混合した後、混合物を２１２℃で加熱処理した。混合物の加熱時間を３５分、４０分、４５分としたものをそれぞれ作製した。その後、得られた粒子をそれぞれ目開き７１０μｍのＪＩＳ標準篩を通過するまで解砕した。次に、解砕された粒子にペイントシェーカーテスト１を行った。こうして、表面が架橋された比較吸水性樹脂を得た。加熱時間３５分のものを比較吸水性樹脂（３−３５）、加熱時間４０分のものを比較吸水性樹脂（３−４０）、加熱時間４５分のものを比較吸水性樹脂（３−４５）とした。
