*Corresponding author: Oleg B. Rudakov, E-mail: robi57@mail.ru
The technical properties of a composite material for construction purposes from birch wood and oligomeric materials, which are formed as wastes of chemical industries, have been studied. These are copolymers of oligomers of butadiene with methyl methacrylate, copolymers of oligomers of butadiene with sulfur and bottoms of rectification of toluene. The influence of the drying temperature and the initial moisture of the samples on the impregnation character was included, including the depth of impregnation and the nature of the combination of the polymer with the wood. Impregnation of the samples was carried out at room and elevated temperatures

the form-stability of low-grade wood - birch, is a composition based on oligomers of butadiene with methyl methacrylate. It can be recommended for use as impregnating composition instead of expensive linseed and castor oils. The most suitable conditions for impregnating birch wood with oligomer solutions are the concentration of the last 30 and 50% by weight, the impregna-
