Poly(vinyl acetate-co-butyl acrylate) latexes were prepared by using semi-continuous emulsion polymerization method in presence of two different protective colloids which were oligomeric N-methylol acrylamide and conventional poly(vinyl alcohol). The effects of these protective colloids on colloidal, surface and film properties of latexes were examined. Poly(vinyl acetate-co-butyl acrylate) synthesized with oligomeric N-methylol acrylamide, which was characterized by FT-IR, NMR and MALDI-TOF MS, was found to have lower viscosity, finer particle size, better latex stability, lower polydispersity, higher Tg and better film forming behavior compared to those synthesized from the poly(vinyl alcohol).
► Poly(vinyl acetate-co-butyl acrylate) latexes were prepared by semi-continuous emulsion polymerization. ► Oligomeric N-methylol acrylamide was used as a new reactive protective colloid. ► It compared with poly(vinyl alcohol) which is conventional protective colloid. ► The latexes obtained with oligomeric N-methylol acrylamide showed a better stability and film forming behavior.
