摘要
Abstract
Blends consisting of polybutene-1(PB-1)and polypropylene-based polyolefin elastomer(POE)were prepared by melt blending method.The phase morphology,tensile mechanical properties,crystallization and melting behavior,crystalline structure,long-period and the relationship between long-period and the composition of blends were studied by confocal Raman microscope system,stretcher,DSC,WAXD,SAXS and other methods.The experimental results indicate that the PB-1 and POE studied here are immiscible.Phase separation is observed in all of the blends.With the increase of PB-1 mass fraction(wPB-1),PB-1 undergoes a phase transition from dispersed to continuous phase,and a phase inversion is observed.The crystalline form and the melting behavior of PB-1 crystals are not influenced by the addition of POE,whereas affected by phase morphology,when wPB-1 is low,a double crystallization peak appears.The crystallization temperature significantly decreases compared with that for the unmixed PB-1 sample.When POE acts as continuous phase,the blends shows high elongation at break and low Young's modulus,while when PB-1 acts as continuous phase,the blends have higher modulus which significantly increases with the increase of wPB-1.关键词
