Estimating the term…
A process for producing water-absorbing polymeric particles by dropletization polymerization in the gas phase, which comprises drying the polymeric particles after the polymerization in a fluidized bed, the water-absorbing polymeric particles themselves, hygiene articles comprising these water-absorbing polymeric particles and also apparatus for implementing the process.
A process for producing water-absorbing polymeric particles by dropletization polymerization in the gas phase, which comprises the polymeric particles after the polymerization being dried and selectively agglomerated and/or postcrosslinked, the drying being carried out in a fluidized bed.
Water-absorbing dropletization polymers in powder form.
Apparatus for producing water-absorbing polymeric particles by a dropletization polymerization in which the polymeric particles after the polymerization are dried and selectively agglomerated and/or postcrosslinked, wherein the apparatus for drying is a fluidized bed apparatus.
Apparatus for producing dried water-absorbing polymeric particles, comprising at least one source of radiation in the upper region of a reaction space and at least one carrier gas feed between the upper portion and the lower portion of the reaction space.
