“…Consequently, there is considerable demand for enhancing the thermal stability of the PVAc using a facile method and inexpensive material to be more suitable and economical in paper coating [8]. Copolymerization of vinyl acetate (VAc) monomer with various petroleum-based monomers including ethylene, butyl acrylate (BA), vinyl chloride, and methyl methacrylate monomers has been applied as a common method to enhance some properties of the PVAc polymer [9][10][11][12][13]. Most of these PVAc copolymers are inexpensive, commercially available polymers with many desirable properties.…”

In this work, lignin-vinyl acetate copolymers containing different fractions of lignin were synthesized by the copolymerization technique. The synthesized copolymer was successfully applied to coat the paper for enhancing its properties and performance. The effects of the lignin-vinyl acetate copolymer on the physicochemical, air permeability and mechanical properties of paper were investigated. The mechanical strength, hydrophilic, and air permeability properties of coated paper were improved with the increasing content of the lignin. Lignin-vinyl acetate copolymer containing 15% lignin coated paper exhibited a 1.86 times increase in the tensile index, 45 times increase in the water contact angle, and a 41.1% reduction in the air permeability compared with uncoated paper. Scanning electron microscopy was applied to study the morphology of the coated and uncoated paper. The results showed that paper surface porosity structure was decreased, while the surface smoothness was enhanced considerably with increasing lignin fraction in the copolymer. Therefore, the successful fabrication of such an enchanting coated paper may afford new potential and great applications in the packaging paper.
