| abstract |
The present invention relates to a salified copolymer obtainable by salification, in an aqueous medium, using at least one amine containing at least one nitrogen-containing heterocyclic group, a copolymer obtained from less a monomer containing cyclic anhydride or carboxylic acid and at least one styrene-based monomer, such as a styrene / maleic anhydride (SMA) copolymer. It also relates to the process for producing this salified copolymer , a composition containing it, and the use of this composition for surface treatment, in particular coating, sizing and finishing, paper or cardboard. |
