The film formation process of emulsion copolymers is obviously of great importance. In the
present work, polymeric particles of butylacrylate and methylmethacrylate are prepared with coreshell
morphology and the relationship between the particle size of an emulsion copolymer system
and the minimum film formation temperature (MFFT), were investigated. By means of different
monomer/emulsifier ratio feed in polymerization system a series of latexes with polymeric
particles ranging 46-960 nm were prepared and MFFT and some final film properties were
studied. Results indicate that decrease in particle size lead to decrease in MFFT and as well
slightly decrease in molecular weight
