Abstract: Polyvinyl acetate (PVAc) water-resistant adhesives are one of the most utilized in the wood industry and classified as D3 durability, exhibiting superior resistance to water and heat when compared to typical Polyvinyl acetate (PVAc) thermoplastic items. The synthesized adhesives by conventional methods were dependent on using inorganic salts, such as aluminum chloride and/or other specific metal via emulsion polymerization seeking to enhance the durability against water and heat. The present investigation aims to improve the durability of polyvinyl acetate (PVAc) to class D3 in accordance with European Standards related to wood adhesives "EN204-205", through emulsion polymerization using core/shell technique. In this method, vinyl acetate was used as specific shell monomer with a mixture of Veova 10 and methyl acrylic acid in very limited ratio as core and ethylene glycol dimethacrylate (EGDMA) as cross-linker. The morphology was investigated by TEM microscopy and FTIR, thermogravimetric analysis was carried out to investigate the heat resistance characteristics. The results showed high water and heat resistance compliments the EN204-205 specifications. [ABSTRACT FROM AUTHOR]
