Abstract

Background: Temperature behavior of a class of PolyEthylene Oxide and Ethylene Glycol (EG) by means of InfraRed spectroscopy as a function of temperature and concentration.

Methods: EG and PEO with Mw of 1000 were purchased from Aldrich-Chemie; To collect the FTIR spectra in the 39°C-80°C temperature range by means of a FTIR Vertex 70V spectrometer by Bruker Optics. Spectra were obtained using an average of 36 scans with a resolution of 4 cm-1 in a window range of 400 ÷ 4000 cm-1. Each measure was performed under vacuum in order to minimize spectral contributions due to residual water vapor and finally the data were processed through the OPUS/Mentor software interface, Mathematica and Matlab.

Results: The addition of EG to PEO increases the thermal restraint of the polymeric matrix due an increase of the H-bond connectivity.

Conclusion: The analysis highlights an increased H-bonded connectivity in the polymeric mixture, which determines a higher resistance to temperature changes of the mixture.

Keywords: Ethylene glycol, PolyEthylene oxide, FTIR spectroscopy, hypsochromic frequency shift, polymeric mixture, H-bonded.
