| Abstract: | The emulsion Polyurethane graft copolymerization modifield by acrylate with core shell structure has been prepared by graft copolymerization in situ.Based on the determination of emulsion particle size and shape by electron microscope and characterization with DSC and TG,and water resistance and solvent resistance,it was found that the acrylate perform graft copolymerization on the polyurethane chain.The thermostability,water resistance and solvent resistance of graft modified polyurethane by acrylate are apparently improved,compared with commerial polyurethane. |

| Keywords: | acrylate polyurethane emulsion graft copolymerization core shell structure. |
