    摘要: A web of superabsorbent polymer and fiber made by an in situ neutralization, wet-laid process, wherein the degree of neutralization of the superabsorbent polymer is partial, preferably less than about 80 mol %. The web exhibits an excellent centrifuge retention capacity property, as compared to prior webs of superabsorbent polymer and cellulosic fiber made by in situ neutralization, wherein the degree of neutralization is total, such as 100 mol % or more.
