摘要

"Dry water absorbent polymers, process for their production, composite, the transport process and the use of hot-melt adhesives in polymer powders.The present invention relates to polymer powders absorbers of water comprising the following components: 0.01 to 20% by weight of a fine particle with a particle size of less than 200 109 m, from 0.001 to 10% by weight of an adhesive thermoplastic, - 60 to 99, 998% in PES Of a particle of polymer absorbing water with a particle size of 200 109 m or more.In which fine particles are stuck on the surface of the particles of the polymer absorber of water by means of a molten thermoplastic adhesive and the polymer absorbers of water still possess a value of fluidity (FFC) within a range between 1 and 13, or a portion of the Soot of up to 6.As well as a process for the production of polymer powders absorbers of water in which the water absorbing polymer powders are obtained by said process. The present invention also refers to a process of transport, a composite, chemical products as well as the use of an adhesive thermoplastic.
