Здійснено алкілування стирену вінілтриметоксисиланом за реакцію Фріделя-Крафтса в присутності безводного AlCl3. Отримано алкокси(4-вінілфенетил)силан. Синтезовані продукти ідентифікували за допомогою 1H, 13C, COSY ЯМР та FTIR спектроскопії. Обговорено розрахунки з використанням методу квантово-хімічної неемпіричної теорії функціоналу густини (DFT) для реакції між вінілтриметоксисиланом і стиреном, здійсненої за орто-, мета- і пара-положеннями. Для теоретичного моделювання використовували програму онлайн-прогнозування "Priroda 04: A quantum-chemical program suite". За різних температур і тисків методом гарячого пресування або екструзії були одержані композиційні матеріали на основі деревної тирси різної дисперсності та синтезованого триметоксисилілованого стирену як в'яжучого й армувального агента зі ступенями силілування (5 %) у присутності різноманітних органічних/неорганічних добавок, антипіренів та антиоксидантів. Досліджено фізико-механічні властивості композитів.
