1. prepare the method for the aqeous suspension of talcum for one kind, described method comprises the step that talcum is suspended in water, wherein said talcum can derive from preceding granulation step, it is characterized in that during described granulation step, using during described suspension step and/or if applicable at least one water-soluble polymers, described water-soluble polymers is characterised in that it is made up of following monomer:

  • A) at least one (methyl) acrylic monomer, andB) monomer of at least one formula (I);

    R–

    (OE) m

    (OP) n

    R’

    (I) Wherein;

    -m and n represent to be less than or equal to 115 integer, what its at least one be non-zero,-OE and OP represent respectively ethylidene oxygen and propylidene oxygen,-R represents to be selected from the polymerizable groups of acrylate group, methacrylate based group, methacryloyl carbamate groups, vinyl groups or allyl group,-R '"'"' represents hydrogen or has the straight chain or the branched alkyl group that are less than 14 carbon atoms.
