Graft polymer, comprising (A) a polymer graft skeleton with no mono-ethylenic unsaturated units and (B) polymer sidechains formed from co-polymers of two different mono-ethylenic unsaturated monomers (B1) and (B2), each comprising a nitrogen-containing heterocycle, whereby the proportion of the sidechains (B) amounts to 35 to 55 wt. % of the total polymer.
L'invention concerne des polymères greffés qui comprennent (A) une base de greffe polymère ne comportant pas d'unités monoéthyléniquement insaturées et (B) des chaînes latérales polymères constituées de copolymères formés de deux monomères monoéthyléniquement insaturés différents (B1) et (B2) comprenant chacun au moins un hétérocycle azoté, les chaînes latérales (B) représentant 35 à 55 % du poids total du polymère.
