1. water-soluble polymer dispersion, it comprises:

  • (i) polymeric composition of gel not substantially, it comprises A polymkeric substance and B polymeric reaction products, the A polymkeric substance is that each polymer chain contains 3.5 or the addition polymer of more active functional group groups, and each polymer chain of B polymkeric substance contains 2 to 3 functional groups that react jointly with said A polymer active functional group;

    Wherein, the addition polymer of described A polymkeric substance is an acrylic copolymer, or hydroxy acrylate or alkylmethacrylate polymer or vinylbenzene/hydroxy acrylate or vinylbenzene/hydroxyl-metacrylate multipolymer, its molecular weight is 500 to 3, between the 000Mn, the active functional group group of said A polymkeric substance is selected from by carboxyl hydroxyl, epoxy group(ing), the polycondensation of the group that the carboxyl acid anhydride is formed-active functional group group or its combination;

    Described B polymkeric substance is a kind of being selected from by polymeric amide, polyester, and epoxy, the condensation polymer of the group that urethane and polyethers are formed, the common reactive functional group group of said B polymkeric substance is a hydroxyl, carboxyl, epoxy group(ing) ,

    oxazolinyl, amino or its combination;

    And the molar ratio of A polymkeric substance and B polymkeric substance is 3;

    1 to 2;


    (ii) water;

    With(iii) contain or do not contain hydrotropy reagent.
