Abstract

Una composizione per il trattamento di un sistema acquoso per impedire la deposizione di scoria provocato da impurezze che formano scoria nel sistema, che comprende (A) un omopolimero idrolizzato di anidride maleica avente un peso molecolare medio ponderale di 400-800 oppure un suo sale solubile in acqua e (B) un polimero acrilico contenente gruppi carbossilici avente un peso molecolare medio ponderale di 800-9500 scelto da un acido poliacrilico, un acido polimetacrilico, un copolimero di almeno due monomeri acrilici, uno di detti monomeri essendo acido acrilico oppure acido metacrilico, un copolimero di acido acrilico o di acido metacrilico con un vinil-carbossilato oppure con uno stirene, un telomero dell'acido fosfinometacrilico, oppure un sale solubile in acqua del polimero acrilico contenente gruppi carbossilici.
