In this research, a new copolyamid was prepared from reaction Aceglutamide with Formaldehyde by esterfication process, and used this copolymer as adhesive between wood – wood surface. Five different weight ( 0.2, 0.4 , 0.6, 0.8 & 1.0 gm ) from the prepared copolymer respectively, were used as adhesive to prepared the specimens of wood / adhesive . Four standard test methods were used to measured the adhesion properties which are; ASTM: D-790, ASTM: D- 695, ISO – 179 &ASTM: D-638 .
The results obtained from these tests indicated that, the specimens of wood / adhesive containing 1.0 gm from the prepared copolymer have high values in all standard tests; Impact strength was 45 MPa, Compressive strength was 40 MPa, Flexural strength was 250 MPa and Tensile strength was 8150.41 MPa ; compared with the other specimens which contain on less weight from the prepared copolymer.
