Zusammenfassung:	PCT No. PCT/FR86/00257 Sec. 371 Date Mar. 23, 1987 Sec. 102(e) Date Mar. 23, 1987 PCT Filed Jul. 22, 1986 PCT Pub. No. WO87/00438 PCT Pub. Date Jan. 29, 1987.The process applies to polymers obtained by a water-in-oil process, that is to say, a reverse emulsion process or a suspension process in reversible phase. The process of fixation of this type of polymer in or on a porous support is characterized in that it comprises the impregnation of the porous support with said reverse suspension or emulsion resulting from the polymerization reaction and the removal of solvent from the support. By said process, complexes are obtained which present improved absorption properties and offer a better holding of the product to the support.
