Dear Sergei,

Determining the Flory interaction parameter is generally not the easiest task.

I warmly recommend to read the following article : Article A Flory–Huggins model based on the Hansen solubility parameters

Eq. 7 in particular can prove most useful in the calculation of χ, as a function of temperature. Try with a = 1 first, and make sure to use the correct values of molar volume at the different T.

Hope this helps
