    摘要: The subject invention provides a surface-crosslinked water-absorbent polymer having improved properties. The subject invention further pertains to a process for preparing such a polymer. Through the use of a preferred primary crosslinking agent coupled with surface crosslinking, desirable absorptive properties are achieved. Suitable primary crosslinking agents include methylenebisacrylamide, bis(acrylamido)acetic acid and its salts, allyl acrylate, allyl methacrylate and esters or amides having both a vinyl and an allyl functionality.

    摘要: A durable, conformable, absorbent, hydrophilic, polymeric latex foam composition having a free absorbent capacity of at least 5 grams of a 0.9 weight percent aqueous saline solution per gram of foam and capable of vertically wicking said aqueous saline solution to a height of greater than about 5 cm. In a preferred embodiment, after compression, the latex foam composition remains thin until wet, whereupon it expands and exhibits a high free absorbent capacity and high vertical wicking height.
