The paper investigates the technology of using new formulations for modifying natural wood based on oligomers obtained from petrochemical waste containing styrene. For the protective treatment of wood, oligomeric materials prepared from by-products of the production of polybutadiene and styrene were used. The oligomers were obtained in the presence of an aluminosilicate catalyst at a temperature of 160-165 0C for 24 hours. It is shown that an increase in the styrene content in the oligomeric product helps to reduce water absorption and swelling of modified wood. It has been established that the introduction of a protective compound into the wood structure, including an oligomer from the by-products of polybutadiene production in combination with KORS varnish, provides effective protection for wood composites.
