Summary

A chemical structure of polyurethane/functionalized silsesquioxane (PUR/PHIPOSS) nanohybrid materials obtained by prepolymer method has been determined. In the 1H NMR and 13C NMR spectra signals from protons and carbon atoms of the characteristic fragments of the PHIPOSS pendant group have been identified. Analysis of the obtained PUR/PHIPOSS elastomers by ATR-FTIR allowed us to estimate the influence of oligosilsesquioxane side groups on the density of the hydrogen bonds and phase separation. It was found that the degree of phase separation increases with increasing PHIPOSS content.


Key words: urethane elastomers, functionalized silsesquioxane, nanohybrid materials, ATR-FTIR spectroscopy, NMR spectroscopy
