7 32 COMPOSITION OF WOOD FOR THE IMPREGNATION V. T. Lebedev, V. Ya. Novikov, S. P. Sheremetov, F. V. Dolinskiy, 1. V. Shiryayeva, V. L. Karpov, V. V. Blinov, and V. I. Toropov Compositions of monomers are known for strengthening wood * by means of impregnation and polymerization with ionizing radiation. The known compositions "of monmomers do not yield the necessary strength of wood and parts made from it. The purpose of the invention is increasing the durability of wood and lengthening the service period of parts made from it by means of impregnation with a composition containing methyl methacrylate in a quantity of 70-93% and 6('f-dichloroethyl ether of vinyl phosphonic acid in a quantity of 30-7% of the volume of the mixture. The orocedure is the following. The wood is evacuated, impregnated with a mixture of monomers of methyl methacrylate and 83'-dichloroethyl ether of vinyl ohosphonic acid in a ratio of 3:1, and polymerized by means of ionizing radiation, for example, the gamma-rays of Co60 in an inert medium at an irradiation dose of 3-5 Mrad. ;FTD-HT

8 Subject of Invention A composition for the impregnation of wood on a base of :4 monomers is characterized by the fact that for the purpose of increasing the durability of wood the composition contains 70-93% methyl methacrylate and 30-7% aa'-dichloroethyl ether of vinyl phosphonic acid. 3 FPD-HT
