Abstract:
A process for producing and a powdery water-absorbing polymers comprising: about 0.01 to 20 wt. % of a fine particle with a particle size of less than about 200 μm; about 0.001 to 10 wt. % of a thermoplastic adhesive; and about 60 to 99.998 wt. % of a water-absorbing polymer particle with a particle size of about 200 μm and above, wherein the powdery water-absorbing polymers have: a flow value (FFC) within the range from about 1 to 13, and/or a dust portion of at most about 6 are disclosed. Also disclosed are a transport process, a composite, chemical products, and a use of a thermoplastic adhesive.
