You used DSC, can you please tell about the environment? was it air or in nitrogen ?

Tb Bo

I run DSC in Argon from room temperature to 550c 10C/min. I have very sharp endothermic peak around 120c and wide and shorter/wide endothermic peak around 300c. Unfortunately we don't have GPC to estimate the MW.
