Polymerization process of the silane coupling agent 3-aminopropyltriethoxy silane – 1H NMR spectra and kinetics of ethanol release

Synthesis and Antimicrobial Activity of New Schiff Bases Having the –SiOR Group (R = CH 3 or CH2CH3), and their Transition Metal Complexes

“…The 1 H nmr spectrum of (1) Hmsb and (5) Hesb in DMSO-d 6 resulted in peaks corresponding to the aromatic protons at 7.38-8.00 ppm and 6.95-7.81 ppm as multiplets [28]. In the ligands, signals at 1.33-2.12 ppm and 0.97-2.12 ppm may be assigned to the [SiA(CH 2 ) 3 A] protons [30]. In the Hmsb Schiff Base ligand, there is a singlet for (AOCH 3 ) protons in the 3.85 ppm [31].…”

Mechanism and Kinetics of Oligosilsesquioxane Growth in the In Situ Water Production Sol–Gel Route: Dependence on Water Availability

“…[4] Among them, the sol-gel process is a well-established one and allows preparation of homogeneous hybrids starting from alkoxide precursors and using hydrolysiscondensation reactions. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] However, in the case of of condensation and the amount of water produced in situ. [1,2] Silsesquioxanes prepared by means of hydrolysis-condensation of organoalkoxysilanes have found applications among the most popular commercial sol-gel products, particularly in the field of coatings.…”

The effect of interfacial interactions on the mechanical properties of polypropylene/natural zeolite composites

“…Surface treatment of fillers with silane coupling agents was carried out through hydrolysis and condensation reactions as follows [18 -20] Silanol groups formed as a result of a hydrolysis reaction react with hydroxyl groups found on filler surfaces to form siloxane bonds through a condensation reaction. As a result of these reactions, silane coupling agents modify the interface by forming a link between the components [19,20].…”
