Industrial growth potential is accompanied by formation and accumulation of waste and by-products which can serve as a valuable raw material for the organic synthesis, and for the various polymer compositions which can be used in the composite materials of various purposes. The important and actual task is to improve the performance properties of the products produced from the recycled materials. One of such perspective directions is their modification. The development of new technologies will expand the range of the products and solve a number of problems in the field of environmental protection. In the present paper we consider the possibility of modifying the polymeric petroleum resin (PPR) based on C9 fraction by the secondary polymethyl methacrylate (PMMA). The modification process was monitored by taking samples from the reactor and chemical analysis of changing of bromine and acid number. Analyzing the results, it can be concluded that the process of modification proceeds in the best way with the PMMA content as modifying agent 5,0 % mass in PPR, the process duration for 6 hours and a temperature of 210 0C. In this case, the acid number reaches a maximum, bromine number is reduced. By the method of the experiment planning according to the Greco-Latin square of the fourth order scheme we defined the conditions of use of this product as the impregnating composition to protect materials made from wood. We used xylene solution of modified PPR with a mass fraction of 51,3 % as an impregnation. The results indicate that the use of modified polymeric petroleum resins as an impregnation of the low value wood species can increase water resistance of products and improve a number of other indicators. Protective treatment of wood materials by modified PPR can effectively protect wood from the negative impacts and extend the service life.
