Abstract
Viene descritta una composizione acquosa gelificabile con tempo di gelificazione ritardato e regolabile in funzione del suo pH, che contiene un polimero organico idrosolubile reticolabile con ione di cromo, un agente reticolante/ritardante malonato di cromo [Cr(malonato)3] ed un tampone acido carbossilico/carbossilato R-COOH/R-COO, dove R indica un radicale alchile contenente da 1 a 3 atomi di carbonio.Il pH della composizione viene regolato ad un valore nell'intervallo da 4,0 a 5,5 in funzione del tempo di gelificazione desiderato.
