Abstract
Abstract In this research, a new polyamide was prepared from reaction Aceglutamide with Formaldehyde by esterfication process, and used this copolymer as adhesive between wood – wood surface. Five different weights (0.2, 0.4, 0.6, 0.8 & 1.0 gm) from the prepared copolymer respectively were used as adhesive to prepare 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 . This adhesive has been used of large quantities of this resin applied in three carpentry workshops in the province of holly Karbala in the area (Ekd carpenters) for a period of six months and has given good results when used in practice in the manufacture of wooden furniture. 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
