It could  be the condensation reaction between modifier macromolecules and  hydroxy of  the wood cell wall macromolecule after  modifier  impregnated into the  internal wood and reduced the  hydroxyl functional groups content  of  the macromolecule inside the timber,which significantly  reduces the aqueous affinity of poplar wood and aqueous absorbency of the wood. The  wood swelling and shrinkage properties thus improved ,and so is its  dimensional stability .
