Paper Title:
Effect of Heat Treatment on the Properties of PB-1/PP Blends
  Abstract

PB-1/PP blend was prepared by blending isotactic polybutene-1 and polypropylene with the ratio of 80/20 through Brabender extruder under melted condition, injected into the standard samples. After heat treatment at 75°C, the crystallization, crystal forms, dynamic mechanical properties, mechanical properties of the blends were studied via differential scanning calorimetry (DSC), X-ray Diffraction (XRD), dynamic mechanical analyzer (DMA) and mechanical testing machines, respectively. It was found that after heat treatment: both the melt temperature and the melting enthalpy of crystal form I in PB-1 component increased, the melt peak of crystal form II decreased gradually, while the melt temperature and melting enthalpy of PP as a disperse phase, maintained unchanged basically; the storage modulus of the blend increased and the tan δ decreased a bit; the mechanical properties of the blend were improved noticeable.
