Résumé :	A comparison of the role of conventional and reactive surfactants also known as surfmers in waterborne latexes and paints was investigated in this study. The systems studied were acrylate latexes prepared by semi¬continuous polymerization in different combinations of surfactants. The effect of surfactant nature on microstructure of latex and film properties were examined. The impact of surfactant migration and its absence was examined by water resistance, hydrophobicity and minimum film forming temperature in the prepared latex films. The nature and integrity of paint film formulated out of these latexes was also discussed. The impact on important properties like dirt pick up resistance, scrub resistance and gloss was illustrated. It has been concluded that reactive surfactants provide the scope of improving water resistance.
