Results and Discussion Crystallization Kinetics Figure 1. DSC thermograms of (a) cold crystallization at a heating rate of 10 °C/min and (b) nonisothermal melt-crystallization at a cooling rate of 5 °C/min for PLLA with various MWs. the effect of various MWs on the isothermal crystallization With decreasing MW, the crystallization peak shifts to higher temperature and becomes much sharper, the crystallization rate increases the crystallization mechanism changes the crystallization cannot be finished
