In this paper, the action mode of NMA in the traditional polyacrylate emulsions was studied by extracting the traditional self-curable PA latex film before curing and comparing the properties of two kinds of model latices A and B. Where model A was prepared according to the traditional self-curable PA latex and the model B was a blend of polyacrylates emulsion and an aqueous solution of poly-NMA. The total proportions of the ingredients were adjusted just the same as of model A. The influences of monomers, the dosages of crosslinking monomer A and emulsifier etc.
