Abstract
Una composizione acquosa gelificabile, con tempo di gelificazione ritardato, contiene un polimero organico idrosolubile e reticolabile con ione di cromo ed un agente reticolante/ritardante costituito da un complesso glicolato di cromo e acido glicolico libero [Cr(glicolato)3 n acido glicolico, con n variabile da 1 a 150].La composizione è economicamente vantaggiosa, consente lunghi tempi di gelificazione anche a temperature elevate e produce gel dotati di una stabilità migliorata in presenza di ioni di metalli bivalenti, in particolare ioni calcio e magnesio.
