Methods to maximize wood hardness and dimensional stability includes chemical modification,compression and heating treatment.In this study,poplar wood( Populus ussuriensis )was treated with different concentrations of a melamine formaldehyde resin,which was low molecular weight and water soluble,and then compressed while being heated.The results showed 47 per cent of antishrink efficiency( ASE) .And the wood specimen were able to retain almost complete fixation when treated with 10 per cent of resin solution and then soaked in room temperature water and treated with 17 5 and 25 per cent of resin solution and then soaked in boiling water.
