Abstract
There is disclosed a method for the ammonia saturation of wood to impart flexibility thereto which includes the step of sealing the surfaces of ammonia-saturated wood with a polymeric film which has limited or no permeability to either or both ammonia and water vapor. Preferably, the polymeric film is flexible so the working of the wood product by bending, twisting, embossing, molding, etc. will not destroy the film. The polymeric film should also be soluble in a selected solvent, thereby permitting its removal after the wood has been formed in a final, desired shape to permit water vapor to re-establish crosslinking of the cellulose chains and restore its natural, rigid condition.
