Summary
The overall crystallization and linear crystal growth kinetics for the (monoclinic) α-form of low molecular mass isotactic poly(propylene) (i-PP) fractions have been studied. Two processes can be found for the overall crystallization study via differential scanning calorimetry (DSC). Based on the nucleation theory, both the half-life time of the first process in overall crystallization kinetics and the linear crystal growth data show two regime transitions, namely, regime I/II and II/III transitions.
