Title (EN) RESILIENT SUPERABSORBENT COMPOSITIONS
(FR) COMPOSITIONS SUPERABSORBANTES ELASTIQUES
Abstract:
(EN) Superabsorbent polymers having improved gel bed resiliency are prepared by dry blending the polymer with a multivalent metal salt to form a mixture; and contacting the mixture with from about 0.1 to 10 weight percent of binder, based on the weight of the mixture.
(FR) Pour préparer des polymères superabsorbants à élasticité améliorée sur lit de gel, on mélange à sec le polymère avec un sel de métal polyvalent pour former un mélange; puis on met en contact le mélange avec une quantité de liant comprise approximativement entre environ 0,1 et 10 pourcent en poids par rapport au poids total du mélange.
