Abstract: The preparation of polyurethane/polyacrylate(PUA) hybrid emulsion is summarized，including blend，seed emulsion polymerization，in-situ polymerization etc. Several factors affecting the properties of PUA emulsion，such as the structure of polyurethane and polyacrylate，the initiator of polymerization and the process of preparation，are discussed. Then the nano-inorganic and cross-linking modification of PUA hybrid emulsion are presented. Further development in the future is indicated.
