摘要
Multiple melting peaks phenomena have been investigated in terms of compositional heterogeneity, crystallization temperature, cooling rate, heating rate, annealing and crystal structure for low ethylene content block and random propylene-ethylene copolymers. The experimental results suggested that the compositional heterogeneity and crystal morphology play an important role in the cause of multiple melting behavior.
