Abstract
The kinetic interplay between crystallization and phase separation in a polymer blend has been examined. By controlling the relative quench depths for liquid-liquid phase separation and crystallization, the growth kinetics of the characteristic length scales of the simultaneous ordering processes show a crossover from crystallization dominated to phase-separation dominated behavior. Based on a scaling argument of the late stage spinodal decomposition, the kinetic crossover is inevitable in a blend where the critical temperature for the liquid-liquid phase separation is above the equilibrium melting temperature of the blend.Citation
