Abstract:The low-temperature self-crosslinkable acrylate emulsion with core-shell structure was synthesized by semi-continuous seed emulsion polymerization technology, using methyl methacrylate (MMA), butyl acrylate (BA), methacrylic acid (MAA), diacetone acrylamide (DAAM) as comonomers, and characterized by FTIR, TEM and DSC. The results show that the particle size and gel amount increased with w(DAAM). When w(DAAM)= 2%, m(ADH)/m(DAAM)=0.8, the adhesion was up to 90%, water resistant time was up to 150h. FTIR test confirmed that crosslinking reaction between DAAM and ADH could occur when film forming at low temperature. DSC analysis indicated that the glass transition temperature of the film after crosslinking is increased by 5.2℃. The TEM images confirmed spherical latex particles with core-shell structure.
