1. , sulfonated graft copolymers comprises:

  • One or more synthons, wherein based on the gross weight of described one or more synthons, 0.1 to 100wt% is that the monoene of at least a band sulfonic acid group belongs to unsaturated monomer, monoene belongs to unsaturated sulfuric ester or its salt;

    WithAt least a hydroxyl be derived from natural material, it is selected from monose or disaccharides or oligose, polysaccharide or natural small molecules,Wherein when the natural material of being derived from of hydroxyl is monose or disaccharides, this hydroxyl be derived from that natural material exists with the amount of 60wt% at least based on the multipolymer gross weight andWherein when the natural material of being derived from of hydroxyl is oligose, polysaccharide or natural small molecules, the natural material that is derived from of this hydroxyl exists with the amount at least about 5wt% based on the gross weight of multipolymer,Wherein said sulfonated graft copolymers free radical grafting copolymerization by described one or more synthons in the presence of the natural material of being derived from of hydroxyl obtains.
