خلاصه مقاله:
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 polymericparticles 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
