FTIR and NMR spectroscopy

The environmentally friendly binder - poly[(trimethoxy)4-vinylphenethyl)] silane was synthesized for the first time via Friedel-Crafts alkylation reaction, which was conducted by the reaction of polystyrene with vinyltrimethoxysilane in the presence of anhydrous AlCl₃.The synthesized polymer was identified using ¹H, ¹³C, ¹H COSY NMR, and FTIR spectroscopy.

Friedel-Crafts alkylation reaction of vinyltri-methoxysilane with styrene was performed in the pres-ence of anhydrous AlCl₃. Alkoxy(4-vinylphenethyl)silane has been obtained. The synthesized products were identified by ¹H, ¹³C, COSY NMR, and FTIR spectroscopy. Calculations using the quantum-chemical non-empirical density functional theory (DFT) method for the reaction between vinyltrimethoxysilane and styrene performed for ortho-, meta- and para-positions were discussed.
