Abstract

Esta invencion esta dirigida a un proceso para producir materiales solidos generalmente particulados dilatables en agua que comprenden polimeros, preferentemente formadores de hidrogel, recubiertos dilatables en agua que estan recubiertos con un agente de recubrimiento que es tal que practicamente no se rompe cuando los polimeros se dilatan en un liquido, por ejemplo, agua o solucion salina. Por ello, el agente de recubrimiento es extensible en estado humedo y comprende ademas un material extensible en estado humedo que tiene una deformacion por tension hasta la ruptura en estado humedo de por lo menos 1 MPa. Normalmente, el agente de recubrimiento comprende tambien un material polimerico elastomerico. La invencion tambien se refiere a materiales solidos (particulados) dilatables en agua que se obtienen mediante el proceso de la invencion.
