Synthesis of Alkyd/Acrylic Hybrid Latexes For Paper Coating Applications
Polymers and High Performance Materials
Novel acrylic latexes based upon vegetable oil macromonomers (VOMMs) were developed for use in paper coatings formulations. The fatty acid pendant functionality internally plasticizes the latex while its unsaturation provides potential sites for oxidative crosslinking. The incorporation of copolymerizable fatty acid derivatives into latexes facilitates improved coalescence during film formation and exhibiting a post-application increase in glass transition temperature. When evaluated against commercial low carboxylation, modified styrene-acrylic latex in paper coating formulations, the VOMM-based latexes exhibited greater hydrophobicity and reduced surfactant migration.
