| 摘要 |
<p>The present invention relates to a process to prepare self-binding pigment particles comprising at least one step a) of grinding one or more binders and one or more mineral materials in an aqueous environment to obtain a suspension, characterised in that , prior to and/or during step a), a copolymer is added in the form of an aqueous solution, said copolymer resulting from the polymerisation of:
2.1)
at least one anionic monomer that is an alkcne;
2.2)
at least one oxyalkylated monomer that is an alkene, wherein the oxyalkyl group has a terminal hydrophobic alkyl, aryl, alkyl aryl or aryl alkyl group having 10 to 32 carbon atoms;
2.3)
optionally, at least one other monomer that is an acrylic ester, a preferred acrylic ester being ethyl acrylate, and/or an unsaturated amide, a preferred unsaturated amide being acrylamide,
as well as to the products obtained by this process, and uses of these products.</p> |
