Abstract
TO solve the problems caused by the migration of small molecule emulsifier during film formation, in this paper, an alkali-soluble resin was used as polymer surfactant instead of small molecule emulsifier to synthesize polyacrylate latexes. The effects of three functional monomers, isobornyl acrylate (IBOA), acrylamide (AM) and hydroxyethyl acrylate (HEA), on the properties of latexes and the adhesion of the relative inks on biaxially oriented polypropylene (BOPP) films were investigated. Among these functional monomers, HEA endows the corresponding ink with the highest adhesion on BOPP thin films due to the fact that HEA can form hydrogen bonds with hydroxyl groups on the surface of BOPP films. The results of the residual monomer detection using gas chromatography (GC) showed that the latex had not only more unreacted residual monomers but also isooctanol due to the saponification of isooctyl acrylate. The residual monomers in the latexes can be nearly completely eliminated when the latexes were subjected to two post-elimination treatments.
