Study of the glass transition of poly(ethylene terephthalate) by gas chromatography

摘要

AbstractThe technique of gas chromatography is used to detect the temperature (Tg) at which the solubility of organic solutes in poly(ethylene terephthalate) (PET) becomes detectable, when the temperature is raised from below to above the glass transition temperature. For a given solute,Tgvaries with the structure of PET. For a given structure of PET,Tgvaries with the nature of the solute.
