The invention relates to a method for impregnating chemicals into wood. In accordance with the invention, the chemicals include a cross-linking agent having carboxyl groups and a low molecular weight oligomer having reactive -OH groups, the cross-linking agent being reactive with -OH groups of the wood and the low molecular weight oligomer; and the chemicals are impregnated into the wood cell wall and the carboxyl groups of the cross-linking agent form ester cross- linking bonds with -OH groups of the wood and/or low molecular weight oligomer in the wood cell wall for improving dimensional stability of the wood product. |
