Abstract: 
The study focuses on obtaining bamboo-based composite materials and new environmentally friendly binders with different degrees of silylation (15-35%) at different pressures and temperatures. The synthesis was carried out using silylated polystyrene (poly[trimethoxy(4-vinylphenethyl)] silane) and styrene as a binder and reinforcing agent in the presence of organic/inorganic additives, antioxidants and antipirene. Poly[trimethoxy(4-vinylphenethyl)] silane, a solid brown substance, was synthesized via an alkylation reaction of vinyltrimethoxysilane and polystyrene, in the presence of anhydrous AlCl3. This paper presents the development of composites for ecological purposes (eco-composites) using bamboo fibers and their basic mechanical properties. The surface structures of the new composites were studied by several techniques including electron microscopy, energy dispersive X-ray microanalysis, bending test, Charpy impact test, thermogravimetry study, and water absorption determination. The new composites are characterized by good mechanical properties, thermal resistance, ecological purity, and water absorption capacity much smaller than the water absorption of existing particle boards.
