Determination the optimal conditions of chemical modification on Poplar wood with Glutaraldehyde and physical properties of products

This research was conducted to determine the optimal conditions for chemical modification of poplar wood with glutaraldehyde and its effect on the physical properties of products. Test samples were prepared according to the standard ASTM-D1037 and impregnated in the laboratory cylinders with Glutara...
