Patent ID: 7144980

Claim:
A method for improving the centrifuge retention capacity property of an in situ wet-laid water sorptive product, said method comprising: (a) forming an aqueous suspension comprising a slurry of (i) a potentially water swellable polymer component; and (ii) a fibrous component; wherein the weight ratio of said polymer component to said fibrous component is controlled to be in a range from about 90: 10 to about 5: 95; (b) forming a composite product from said suspension; (c) contacting said composite product with an amount of an aqueous solution of a neutralizing agent sufficient to achieve a partial degree of neutralization of the acid groups of the polymer component of said composite product; and (d) drying said neutralized composite product to achieve a water sorptive product of superaborbent polymer component with fibrous component, said water sorptive product having improved centrifuge retention capacity properties.
