Abstract:
1. Treated water-absorbing polymer particles comprising: from about 0.01 to about 20 percent by weight of the polymer of a fine particle with a particle size of less than about 200 μm; from about 0.001 to less than 0.3 percent by weight of the polymer of a thermoplastic adhesive; and from about 60 to about 99.998 percent by weight of the polymer of a water-absorbing polymer particle with a particle size of about 200 μm and above, wherein wherein the treated water-absorbing polymer particles are prepared by a production process and the fine particles are bound to the surface of the water-absorbing polymer particles by the thermoplastic adhesive during the production process for the treated water-absorbing polymer particles, and the treated water-absorbing polymer particles have either a flow value (FFC) comprising from about 1 to about 13 according to the Determination of the FFC Value set forth in the present application, or a dust portion comprising at most about 6 according to the Determination of the Dust Portion method set forth in the present application.
