Abstract
Description
a)酸基を有し、少なくとも部分的に中和されている、少なくとも1種のエチレン性不飽和モノマー、
b)少なくとも1種の架橋剤、及び
c)少なくとも1種の開始剤
を含むモノマー水溶液と、発泡した界面活性剤水溶液とを混合することによってモノマー調製物を生成することを含む、方法によって達成された。
この後に記載される、「WSP」と称される標準試験方法は、「Standard Test Methods for the Nonwovens Industry」、2005年版、国際的戦略パートナーのEDANA (Herrmann-Debrouxlaan 46、1160 Oudergem、Belgium、www.edana.org)とINDA (1100 Crescent Green、Suite 115、Cary、North Carolina 27518、米国、www.inda.org)とによる共同刊行、に記載されている。この刊行物は、EDANAとINDAとの両方から得ることができる。
水分率は、EDANA推奨試験方法No. WSP 230.2 (05)「Mass Loss Upon Heating」によって測定される。
遠心保持容量(CRC)は、EDANA推奨試験方法No. WSP 241.2 (05)「Fluid Retention Capacity in Saline, After Centrifugation」によって測定される。
21.0g/cm2の圧力下での吸収率(AUL)は、EDANA推奨試験方法No. WSP 242.2 (05)「Absorption Under Pressure, Gravimetric Determination」によって測定される。
49.2g/cm2の圧力下での吸収率(AUHL)は、21.0g/cm2(0.3psi)の圧力ではなく49.2g/cm2(0.7psi)の圧力が設定されることを除いて、EDANA推奨試験方法No. WSP 242.2 (05)「Absorption Under Pressure, Gravimetric Determination」と同様に測定される。
超吸収体粒子の抽出分の含有量は、EDANA推奨試験方法No. WSP 270.2 (05)「Extractable」によって測定される。
水性抽出物(ST)の表面張力を測定するために、0.50gの超吸収体粒子を小さいビーカーに量り入れ、40mlの0.9重量%の塩溶液と混合する。ビーカーの内容物を磁気撹拌子で3分間500rpmで撹拌し、次いで2分間静置する。最後に、上清水性相の表面張力を、K10-STデジタル張力計(Kruss GmbH社、ハンブルグ、ドイツ)又は白金板を有する同等な機器で測定する。測定は23℃の温度で行う。
自由膨潤速度(FSR)を測定するために、1.00g(=W1)の超吸収体粒子を25mlのビーカーに量り入れ、その底部の上に均一に広げる。次いで20mlの0.9重量%の塩化ナトリウム溶液をディスペンサーによって計量して第2のビーカーに入れ、このビーカーの内容物を第1のビーカーに素早く添加し、ストップウォッチを始動させる。塩溶液の最後の液滴が吸収されたらすぐに(これは、液体表面の反射の消失によって認識される)、ストップウォッチを止める。第2のビーカーから注がれ、第1のビーカー中のポリマーによって吸収された液体の正確な量を、第2のビーカーを再び量ることによって正確に測定する(=W2)。ストップウォッチで測定した、吸収に必要とされる時間間隔をtと表記する。表面上での最後の液滴の消失を、時間tとして決定する。
FSR[g/gs]=W2/(W1×t)
しかしながら、超吸収体粒子の水分率が3重量%より多い場合は、重量W1はこの水分率を考慮するように補正するべきである。
0.3psi(2070Pa)の圧力下での膨潤ゲル層の透過性(SFC)を、EP2535698A1に記載されるように、1.5gの重量の超吸収体粒子を用いて、膨潤ゲル層の尿透過性測定値(UPM)として測定する。流量は自動的に検出される。
SFC[cm3s/g]=(Fg(t=0)×L0)/(d×A×WP)
式中、Fg(t=0)はNaCl溶液の流量(単位g/s)であり、これは、流量測定のFg(t)データの線形回帰分析を使用してt=0に外挿することによって得られ、L0はゲル層の厚さ(単位cm)であり、dはNaCl溶液の密度(単位g/cm3)であり、Aはゲル層の面積(単位cm2)であり、WPはゲル層上の静水圧(単位ダイン/cm2)である。
0.3psi(2.07kPa)の圧力下での液体の体積吸収率(VAUL)のために、τ値をWO2014/079694 A1の39頁及び40頁に記載されている試験方法「Volumetric Absorbency Under Load (VAUL)」によって測定する。τ値は、そこでは「特性膨潤時間」として記載される。
