The subject invention pertains to an aqueous fluid absorbent polymer having a superior balance of absorptive properties. In particular, the subject invention provides an aqueous fluid absorbent polymer characterized by a centrifuge capacity of at least 25 grams/gram, and an absorption under a 1.0 psi (70,000 dynes/cm2) load of at least 15 grams/gram. The subject invention further provides a process for preparing such polymers, which process employs an inhibitor during heat-treatment of the polymer. The subject invention further provides an absorbent structure comprising a fiber matrix and an aqueous fluid absorbent polymer characterized by a centrifuge capacity of at least 25 grams/gram, and an absorption under a 1.0 psi (70,000 dynes/cm2) load of at least 15 grams/gram. |
