前記実施例及び比較例の高吸水性樹脂に対して次のような方法で物性評価を行い、測定された物性値は下記表1に示すとおりである。
表面架橋前のベース樹脂粉末2.5gを4ml体積の円筒形コラムに充填した後、イソプロピルアルコール(IPA)で占める体積を基準に内部気孔体積を定義した。このような気孔体積の算出結果と、電子顕微鏡(X50)分析結果により、気孔度(気孔体積分率)を確認した。
ヨーロッパ不織布産業協会(European Disposables and Nonwovens Association、EDANA)の規格であるEDANA WSP241.2に従い実施例及び比較例の高吸水性樹脂に対して、無荷重下の吸収倍率による遠心分離保持能(CRC)を測定した。
CRC(g/g)={[W2(g)−W1(g)]/W0(g)}−1
W0(g)は高吸水性樹脂の初期重量(g)であり、
W1(g)は高吸水性樹脂を使用せず、遠心分離機を用いて250Gで3分間脱水した後に測定した装置重量であり、
W2(g)は常温で0.9重量%生理食塩水に高吸水性樹脂を30分間浸水して吸収させた後、遠心分離機を用いて250Gで3分間脱水した後に、高吸水性樹脂を含んで測定した装置重量である。
実施例及び比較例で製造された高吸水性樹脂のうち300〜500μmの粒径を有する試料1.0gを250mLの三角フラスコに入れた後、200mLの0.9重量%の塩化ナトリウム水溶液からなる生理食塩水に入れて250rpmで攪拌しながら1時間自由膨潤(free swelling)させた後、フィルターペーパー(filter paper)で水溶液をろ過した。ろ過した溶液を0.1N苛性ソーダ溶液でpH10まで1次適正した後、0.1N塩化水素溶液でpH2.7まで逆適正を実施して得られた適正量からEDANA法のWSP270.3により高吸水性樹脂内の水可溶分の含有量(重量%)を計算した。
実施例及び比較例で製造された高吸水性樹脂のうち300〜500μmの粒径を有する試料2.0gを100mLのフラスコに入れた後、50mLの0.9重量%塩化ナトリウム水溶液からなる生理食塩水に入れて600rpmで攪拌しながら自由膨潤させた後、攪拌によって生じる液体の渦巻き(vortex)がなくなり、なめらかな表面ができる時までの時間を測定した。
