Improved water absorbent copolymers of copolymerizable carboxylic acids and acrylic or methacrylic esters

摘要: Polymers of unsaturated copolymerizable carboxylic acids, at least one acrylic or methacrylic ester containing an alkyl 10 to 30 carbon atoms, and nitrile amide, optionally with a small amount cross-linking agent, rapidly absorb retain large quantities water ionic fluids, are useful in disposable nonwoven articles.
