خلاصه مقاله:
The methods of the main mechanical relaxation temperatures, i.e. dynamic mechanical thermal analyser (DMTA), and differential scanning calorimetry (DSC) were considered to determine thechange at the glassy-rubbery transition, phase behavior, and the consequence effects on the gas transport properties of ABS/PEG blend membranes (prepared by blending ABS with polyethylene glycol (PEG) with different molecular weights). The results obtained by DMTA measurement show only one main glass transition peak for ABS/PEG membranes. The PEG flexible EO bondscause to lowering the maximum value of tan δ peaks and a shift of glass transitions to lesser values. The state of dispersion for the blends with low PEG molecular weights and the occurrence of phase separation for that of high PEG molecular weights, concluded from the DSC test
