Ecologically pure new composite materials with high-technical characteristics are made on the basis of wood sawdust and sillylated styrene. These composite materials are obtained on the basis of a new binder triethoxylated styrene (at different pressures, temperatures). The binder used simultaneously acts as both a binder and a reinforcement agent. The surface structure of the new composite materials was studied by means of Scanning Electron Microscopy and Ener-gy Dispersive X-ray Micro-analysis, thermal, physical-mechanical properties. For composites te-nsile strength at bending, impact viscosity, thermogravimetric stability and water absorption co¬efficient have been examined. Optimal conditions for obtaining new, environmentally safe composites have been established. The obtained composites are characterized by high mecha-nical properties, thermal resistance, ecological purity and low water absorption capacity4%, which is one order of magnitude smaller than the water absorption of existing particle board.
