Thermoanalytical evaluation of readily available reference polymers

摘要: A commercial set of polymers has been characterized by TG-DTA, DSC, TMA, FTIR spectroscopy and X-ray diffraction analysis (XRD). Thermal mechanical stability, as well the polymer glass transition temperature,T g, melt m, have documented. There is a good correlation between measuredT g andT m values published data. The degree crystallinity for polyethylene verified XRD. credibility stability these reference based on comparison their thermal properties, over wide range temperatures from two versions set, in 1979 (A) 1994 (B). properties stood test time are reliable, readily available consistent.
