The present invention is directed to a process for the preparation of polysaccharide grafted latex particles wherein the polysaccharide has .szlig.- 1,4 linkages, wherein the process comprises core/shell emulsion polymerisation. Preferably, the process comprises a single step of preparing the latex particles by emulsion polymerisation of latex monomers with the simultaneous grafting of the polysaccharide.
La présente invention concerne un procédé de préparation de particules de latex avec greffage d'un polysaccharide présentant des liaisons .szlig.-1,4; ledit procédé comprenant une polymérisation en émulsion noyau/enveloppe. De préférence, le procédé comprend une seule étape qui consiste à préparer les particules de latex par polymérisation en émulsion de monomères de latex avec greffage simultané du polysaccharide.
