Title (EN) POLYMER COMPOSITION, ITS USE AND A SURFACE SIZE
(FR) COMPOSITION DE POLYMÈRE, SON UTILISATION ET PRODUIT D'ENCOLLAGE DE SURFACE
Abstract:
(EN) The invention relates to a water-soluble polymer composition obtained by polymerizing in an aqueous polymerisation medium, which comprises degraded starch, at least following monomers: acrylamide and/or methacrylamide, and > 2 mol-% of at least one unsaturated mono- or dicarboxylic acid(s) or salts thereof. The polymer composition has an anionic net charge at pH 7 and a dry solids content of > 5 weight-%. The invention relates also to the use of the polymer composition for surface sizing of paper, board or the like as well as to a surface size composition comprising it.
(FR) L'invention concerne une composition de polymère soluble dans l'eau, obtenue par polymérisation dans un milieu de polymérisation aqueux, qui comprend un amidon dégradé, au moins les monomères suivants : acrylamide et/ou méthacrylamide et > 2 % en mole d'au moins un acide monocarboxylique ou dicarboxylique insaturé ou des sels correspondants. La composition de polymère présente une charge anionique nette à pH 7 et une teneur en solides secs > 5 % en poids. L'invention concerne également l'utilisation de la composition de polymère pour l'encollage de surface de papier, de carton ou analogue, ainsi qu'une composition d'encollage de surface la comprenant.
