Abstract
A method of treating a cellulose-based material, for example wood and engineered wood is provided, wherein the process involves the following steps: selecting and placing the cellulose-based material in a treatment chamber; impregnating the cellulose-based material with an impregnating agent consisting of an aqueous solution comprising a fluid suitable for esterification; facilitating a hydrolysis process whereby the impregnating agent reacts resulting in the formation of esters and polyesters inside the cellulosed-based material.

A method of treating a cellulose-based material, for example wood and engineered wood, wherein the process involves the following:
- a) selecting and placing the cellulose based material in an impregnation chamber;
- b) impregnating the cellulose based material with a solution containing a monomer(s) to be esterified;
- c) placing the impregnated cellulose-based materials in a modification chamber;
- d) elevating the pressure in the modification chamber to above normal atmospheric pressure;
- e) heating the pressurized impregnated cellulose-based material to above ambient temperature until polymerization has been completed;
- and
- f) lowering the temperature to ambient temperature and lowering the pressure in the chamber to atmospheric pressure.
