A superabsorbent, thermoplastic polymeric composition comprising:(A) from about 86 to about 98 percent by weight, based on the total weight of the composition, of a poly(oxyethylene) diol soft segment having a weight average molecular weight in the range of from about 5,000 to about 50,000; and(b) from about 2 to about 14 percent by weight, based on the total weight of the composition, of a hard segment which has a melting point above ambient temperature and below the temperature at which decomposition of either the composition or the soft segment takes place, is essentially insoluble in water, and phase separates from the soft segment, said hard segment being selected from the group consisting of polyurethanes, polyamides, polyesters, polyureas, and combinations thereof;wherein the soft and hard segments are covalently bound together by means of urethane, amide, ester, or secondary urea linkages or combinations thereof.The compositions are especially well suited for the preparation of nonwoven webs by meltblowing, coforming and spunbonding processes.
