を含有するモノマー溶液の液滴を該液滴を取り囲む気相中で重合させることによって製造する方法において、前記モノマー溶液中に水不溶性の無機塩が懸濁されており、かつ前記ポリマー粒子が少なくとも150μmの平均直径を有することを特徴とする方法によって解決された。
(A)上部液体透過性カバー
(B)下部液体不透過性層
(C)以下のものを含有する(A)と(B)の間にあるコア
10〜100質量%の本発明による吸水性ポリマー粒子
0〜90質量%の親水性繊維材料
好ましくは
30〜100質量%の本発明による吸水性ポリマー粒子
0〜70質量%の親水性繊維材料
特に好ましくは
50〜100質量%の本発明による吸水性ポリマー粒子
0〜50質量%の親水性繊維材料
特に好ましくは
70〜100質量%の本発明による吸水性ポリマー粒子
0〜30質量%の親水性繊維材料
最も好ましくは

0〜10質量%の親水性繊維材料
(D)場合により、コア(C)の直上及び直下にある組織層、
(E)場合により、(A)と(C)の間にある吸収層。
測定は、別に記載がない限り、23±2℃の環境温度及び50±10%の相対空気湿度で実施される。吸水性ポリマーは、測定前に良く混和する。
0.3psi(2070Pa)の圧力負荷下での膨潤されたゲル層の液体通過性は、EP−A0640330号中の記載と同様に、高吸収性のポリマーからなる膨潤したゲル層のゲル層透過性として測定され、この場合上記の特許出願明細書第19頁及び図8に記載の装置は、ガラスフリット(40)がもはや使用されず、プランジャー(39)が円筒体(37)と同様のプラスチック材料からなり、今や全載置面にわたって均一に分布するように21個の同じ大きさの孔を含むように十分に変更した。測定の方法及び評価は、EP−A0640330号に対して不変のままである。通過流量は、自動的に捕捉される。
SFC [cm3s/g]=(Fg(t=0)×L0)/(d×A×WP)
上記式中、Fg(t=0)は、g/秒でのNaCl溶液の流量であり、これは、流量測定のデータFg(t)の線形の回帰分析に基づいてt=0に対する外挿法によって得られ、L0は、cmでのゲル層の厚さであり、dは、g/cm3でのNaCl溶液の比重であり、Aは、cm2でのゲル層の面積であり、かつWPは、dyn/cm2でのゲル層上の静水圧力である。
吸水性ポリマー粒子の遠心保持能力は、EDANA(European Disposables and Nonwovens Association)によって推奨された試験方法No.441.2−02"遠心保持能力(Centrifuge retention capacity)"によって測定される。
14.6kgのアクリル酸ナトリウム(水中37.5質量%の溶液)及び1.4kgのアクリル酸を、22.4gの15エトキシ化されたトリメチロールプロパントリアクリレートと混合した。該溶液を、加熱され窒素雰囲気で充填された液滴化塔(Vertropfungsturm)(180℃、12mの高さ、2mの幅、並流で0.1m/sのガス速度)中に液滴化した。計量供給速度は、16kg/hであった。液滴化プレートは、170μmの穿孔を37個有していた。液滴化プレートの直径は、65mmであった。開始剤とリン酸カルシウムを、液滴化装置の直前で、ベンチュリミキサを介してモノマー溶液へと計量供給した。開始剤としては、2,2′−アゾビス[2−(2−イミダゾリン−2−イル)プロパン]ジヒドロクロリドを水中に溶かした15質量%の溶液を使用した。リン酸カルシウムは、30質量%の水溶液(Rhodia社のTCP130型のリン酸カルシウム分散液)として使用した。開始剤溶液の計量供給速度は、0.224kg/hであった。液滴化塔からのガス出口温度は130℃であった。得られたポリマー粒子の平均粒径は、270μmであった。引き続き、得られた吸水性ポリマー粒子を分析した。これらの結果を第1表にまとめる。
