Physical properties of poplar wood saturated with methyl methacrylate

The aim of this study was to provide Poplar’s wood-polymer composite to improve the physical properties and practical use in industry. Accordingly, a sample test was done with monomer methyl methacrylate with the method of filled cell saturation and then heating in an oven to be polymerized at 140 and 150 °C and times of 4 and 5 h. After providing poplar’s wood-polymer composite, the physical characteristics of poplar wood such as water adsorption, special gravity, dimensional change were analyzed. The results of one-way analysis of variance showed significant changes in all experimental variables. In temperature changes, only the percentage of polymer establishment was significant, while no significant difference was found in the changes. In the analysis of factorial variance, the dependent effect of temperature and time, the only significant effect was percentage of polymer establishment and water adsorption. The results showed that all the physical properties including water absorption, dimensional change and specific gravity in this study were improved compared to the control.
