SynopsisIn the present paper, the emulsion polymerization of methyl methacrylate-butyl acrylate and styrene-ethyl acrylate were carried out. Polymer emulsions with latex particles of different morphology were prepared. The relationship between the minimum film formation temperature of the polymer latexes and the morphology of the latex particles were studied, and the film-forming mechanism of the polymer latexes with varied particle morphology was aIso discussed.
