A new design of hot-stage (temperature controlling cell) and methodology were developed for investigating the kinetics of fast phase transitions of polymers at higher supercooling. The contact cooling rate of the hot-stage can be increased up to 1000 degrees C/s (between 200 degrees C and 80 degrees C) by means of flowing liquid cooling, the response rate of the whole device due to immediate temperature measurement and an original automation unit. This design enables one to study isothermal crystallization of polyethylene down to 80 degrees C, and its relative simplicity makes it suitable for routine measurements. Description of the parameters of the automation unit and the heating/cooling cell are reported.
