More Information
Summary:Disclosed is a copolymer of a dextrin and at least two hydrophobic monomers made up of styrene and at least one straight or branched acrylic C1-C4 ester. The invention also relates to the manufacturing method thereof and to the use thereof in paper coating. The copolymer has high dextrin content (>60 wt % relative to the weight of the dextrin and the hydrophobic monomers) so as to favor the biosourced aspect of the material, and provides very good hydrophobicity for the paper sheet.
