In this study,plantation poplar wood samples were acetylated with acetic anhydride and then densified by hot pressing along the transverse direction. The effects of weight percentage gain（WPG）,compression rate,hot pressing time and hot pressing temperatures on physical and mechanical properties of the samples were investigated. Results showed that the acetylated wood with 20.56% WPG at 180°C for60 min to a 40% compression rate showed superior physical and mechanical properties as well as less compression rebound. The finished product could be used for manufacturing solid wood floors,furniture and plank road.
