Abstract
In a method for treating wood, wherein a wooden body is impregnated with a polymerizable compound which is polymerizable by oxidation, the polymerizable compound is brought into contact with an oxidizer in the wooden body in order to polymerize the polymerizable compound in situ. The polymerizable compound applied therein comprises a heterocyclic compound with nitrogen and/or sulphur as heteroatom. The oxidizer is brought into solution and the wooden body is saturated with a solution of the oxidizer. The wooden body is subjected to a vapour phase of the heterocyclic compound under an increased pressure and the heterocyclic compound is polymerized in situ in the wood.

A method for treating wood, wherein a wooden body is impregnated with a polymerizable compound which is polymerizable by oxidation and the polymerizable compound is brought into contact with an oxidizer in the wooden body in order to polymerize the polymerizable compound in situ, wherein the polymerizable compound comprises a heterocyclic compound with nitrogen and/or sulphur as hetero-atom, the method comprising:
- bringing said heterocyclic compound into a vapor phase by heating a liquid containing said heterocyclic compound to a boiling point of the heterocyclic compound;
- impregnating the wooden body with the oxidizer as a liquid to provide an impregnated wooden body;
- and
- subjecting the impregnated wooden body to an underpressure and, subsequently, to said vapour phase of the heterocyclic compound under an increased pressure, wherein the heterocyclic compound is polymerized in situ in the wooden body under the influence of the oxidizer.
