and chemical strengths are required. Among crosslinkable polymers, those with film forming capability (e.g.,coatings and adhesives) are of particular interest. This work investigated the miniemulsion polymerization ofvarious acrylic monomer formulations in the presence of an iso-butylated melamine-formaldehyde resin with theaim of obtaining waterborne nanocomposites with controlled crosslinkable capabilities. Variation of the acrylicmonomer formulation showed a significant influence on the degree of crosslinking, and consequently, on thefinal properties of the acrylic/melamine nanocomposite particles, their coalesced films at room temperature andthose cured at high temperature. Thereafter, these results offer the opportunity of obtaining waterborne acrylic/melamine nanocomposites with different post-crosslinking capabilities
