Ambient temperature self-crosslinking acrylic latexes were prepared through semicontinuous emulsion polymerization using 3 different polymerizable alkoxysilanes, i.e. vinyl tri silane (A172), Vinyl triethoxy silane and γ-methacryloxypropyl trimethoxy silane (A174). The hydrolysis of these siloxanes under different pH was characterized, and dependence of the latex and polymer properties on these siloxanes and their incorporated amounts in the polymers was studied.
