1. a kind of method for preparing graft copolymer, the method include the following material of reactively blending in an extruder:

  • I) hydrophobic polymer of at least one glass transition temperature more than 120 DEG C, andIi) at least one hydrophilic polymer,Wherein described hydrophobic polymer and the hydrophilic polymer are not comprising can make the hydrophobic polymer and the hydrophilicPolymer react with each other the temperature range of the functional group and extruder mixed zone to form graft copolymer be from 280 DEG C to 350 DEG C,Thus obtain graft copolymer in an extruder by reactively blending.
