Synthesis of crosslinked poly(orthosilicate)s based on cyclohexanediol derivatives and their swelling properties

Abstract

Condensations of tetraethyl orthosilicate (TEOS) with cyclohexanediol derivative monomers at moderately high temperatures resulted in the creation of crosslinked poly(orthosilicate)s. The structural and thermal properties of the crosslinked poly(orthosilicate)s polymers were determined by Fourier transform infrared spectroscopy, solid-state 13 C and 29 Si crosspolarization magic angle spinning nuclear magnetic resonance, thermogravimetric analysis and differential scanning calorimetry. The synthesized crosslinked polymers were found to be insoluble in common organic solvents, such as tetrahydrofuran, dichloromethane, benzene and acetone, although they displayed swelling abilities in these solvents. The swelling ability of the crosslinked polymers was examined by the swelling test, swelling kinetics and desorption kinetics. The results suggest that crosslinked poly(orthosilicate)s based on cyclohexanediols can find good use as absorbents for organic solvents.

Hydrophobic poly(alkoxysilane) organogels as sorbent material for oil spill cleanup

“…Previously, we synthesized crosslinked poly(orthosilicate)s based on tetraethyl orthosilicate (TEOS) with hydroxyl functional monomers (cyclohexanediols (Karadag et al, 2010), cyclohexanedimethanols and linear aliphatic diols which have fast and high organic solvent absorption properties with oil-derived pollution, reusability and good thermal stability.…”

Poly(alkoxysilane) reusable organogels for removal of oil/organic solvents from water surface

“…The poly(orthosilicate)s were prepared by condensing tetraethyl orthosilicate (TEOS) with hydroxyl functional monomers (based on cyclohexanediols, (Karadag et al, 2010), cyclohexanedimethanols , linear aliphatic diols ) and showed good organic solvent absorption properties.…”

Novel poly(orthosilicate)s based on linear aliphatic diols: Synthesis, characterization, and swelling properties

“…All of the synthesized polymers were thermally stable and had good, rapid sorption features for organic solvents such as dichloromethane (DCM), tetrahydrofuran (THF), dichloroethane, acetone, and a dry‐cleaning fluid blend. Using the same methodology we previously reported, we have synthesized crosslinked poly(orthosilicate)s with tetraethyl orthosilicate (TEOS) and hydroxyl monomers (based on cyclohexanediol49 or cyclohexanedimethanol50, 51). The obtained polymers are thermally stable and have very fast and efficient organic solvent absorption properties.…”
