thermal transitions and melting/fusion enthalpies were measured using
a Mettler Toledo DSC2 calorimeter equipped with an HSS7 sensor and
a TC-125MT intercooler. The endotherms were recorded when the temperature
was raised from 25 to 160 °C, cooled back to −50 °C,
and reheated to 150 °C, at a rate of 10 °C min–1 with a nitrogen flow of 60 mL min–1. The crystallization
temperature (Tc) from the cooling scan
and melting temperature (Tm) from the
melting temperature during the second heating scan were taken as the
peak value of the crystallization or melting enthalpy in triplicate
measurements.
