HIGHLY WATER-ABSORBING MATERIAL COMPOSITION HAVING SMALL WATER-SOLUBLE CONTENT

摘要: PURPOSE:To provide a highly water-absorbing material composition retaining high ratio, having small water-soluble content and suitable for paper diapers, sanitary materials, etc., by compounding water-insoluble resin cationic dissociated groups with anionic groups. CONSTITUTION:(A) A (e.g. polyethyleneimine or polyallylamine) potassium permanganate consumption amount of <=20mg/l, the being determined measuring an aqueous solution obtained dispersing 1g in 1l water to extract components contained is compounded (B) hydrolysate starch-acrylonitrile graft copolymer) wt. ratio 1:99 99:1.
