Abstract
The invention relates to a support provided with super-absorbent material to be manufactured by causing suitable monomers to polymerize in the presence of a catalyst in order to obtain a polymer solution, adding a cross-linking agent to the polymer solution to obtain a pasty composition, subsequently applying the composition on or in a support and allowing the applied composition to dry and cross-link in order to obtain the support with the super-absorbent material, wherein microspheres are added to the paste.

A method for preparing a microporous full surface superabsorbent polymer coating comprising adding a cross-linking agent to a polymer solution, adding gas-filled polymeric microspheres to the polymer solution prior to, during or after the addition of the cross-linking agent and applying the coating as a paste to a support.
A microporous full surface superabsorbent polymer coating comprising a cross-linked polymer and gas-filled polymeric microspheres.
A microporous full surface superabsorbent polymeric coating prepared according to the steps of adding a cross-linking agent to a polymer solution and adding gas-filled polymeric microspheres to the polymer solution prior to, during or after the addition of the cross-linking agent.
