What is glass transition temperature (Tg)? What are the units of glass transition temperature? Which type of polymers undergo glass transition? What are the examples of polymers with high or low Tg? What is the difference between Tg and Tm? Why is it important to identify the Tg of ...
The measurements have been performed on a series of polyethylene terephthalate (PET), polycarbonate (PC) and polyethylene terephthalate glycol (PETg) samples. Different temperatures were needed to explore the range of the glass transition domain of each polymer. The results compared to calorimetric and...

Temperature Modulated Differential Scanning Calorimetry (TMDSC) is used to estimate Cooperative Rearranging Region (CRR) average sizes for polymer/clay nanocomposites, obtained by mixing polyethylene 1,4-cyclohexylenedimethylene terephthalate glycol (PETg) filled and organically modified nanoclay (C15A) ...
A constitutive model is developed to capture the rate-dependent stress–strain behavior of an amorphous polymer (poly(ethylene terephthalate)-glycol (PETG)) at temperatures in and above the glass transition ( θ g). As a polymer goes through its glass transition, it exhibits a dramatic decrease...
In order to examine the proposed method, the stress responses of two representative polymers, PETG and PC, across the glass transition are experimentally obtained and compared with the model predictions. It is shown that, by adopting the parameter of critical strain, the variable-order fractional ...
In GMP, the mold and the platens are heated by infrared lamp to above 50–100 ◦C of glass transition temperature (Tg) for about 180 s. Since glass is transparent in infrared light, it cannot be directly heated by the infrared lamp, but instead, has to be indirectly heated by the ...
