The effect of thermal history onβ-nucleated iPPwas systematically investigated by comparing the variance of crystallinemicrostructures andmechanical property of stepwise crystallized sample and annealed sample, which experienced different thermal history. Themechanical property tests exhibit that that the toughness of stepwise crystallized sample and annealed sample were both decreased compared to control sample, while the tensile strength of the stepwise crystallized sample increased slightly. Structure investigation showed that theα-relaxation peak, which is related to the assignment of chains in rigid amorphous phase,moved to the high temperature region for stepwise crystallized sample, while itmoved to the low temperature region for annealed sample. The results indicated the weakening in rigid amorphous fraction (RAF) and the increase in lamellar thickness ofβ-iPP after stepwise crystallization treatment. For annealed sample, the RAF strengthened and lamellar thickness decreased slightly after thermal treatment. Amechanismof crystallinemicrostructures evolution of restricted area between themain lamellar under different treatments was proposed.
