| 摘要 |
<p>The present invention relates to a salified copolymer that can be obtained by salification, in an aqueous medium, using at least one amine containing at least one nitrogenous heterocyclic group, of a copolymer obtained from at least one cyclic anhydride-based or carboxylic acid-based monomer and from 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, to a composition containing same, and also to the use of this composition for surface-treating, in particular coating, sizing and finishing, paper or cardboard.</p> |
