Dear Experts,

I would like to know that how can i calculate the glass transition temperature of a polymer? ( Without doing scripting)

In papers it is said that we can calculate it using Annealing method but when i tried the same i am not getting what i want. i.e i get the densities at lower temperatures but not on the higher temperatures.
to draw the graphs i also need the densities at higher temperatures......
waiting for a positive response
