چکیده	This research investigated the effect of chemical modification with vinyl acetate in combination with different coupling agents (maleic anhydride, 3-(trimethoxysilyl) propyl methacrylate and glycidyl methacrylate) on chemical structure and physical properties of poplar wood. Samples were impregnated with chemicals using vacuum-pressure method following by vinyl acetate. Fourier transform infrared analysis results confirmed cell wall chemical modification, that was more obvious for glycidyl methacrylate ones. Dimensional stability of resultant composite enhanced via crosslink formation between modified wood and polymer, which affected by cell wall modification rather than in situ polymerization. In comparison of coupling agents, glycidyl methacrylate mostly improved the physical properties of wood as well as combined modified composites.
