Coupling effects of toughening modification and solid die-drawing process on the morphology and mechanical properties of PP/TMB-5 composites with POE

A traditional strategy for toughening modification of polypropylene (PP) is to utilize the excellent impact resistance of β-PP by introducing β-phase nucleating agent (β-NA) into PP matrix. In this work, highly oriented PP/TMB-5 composites and PP/POE/TMB-5 composites were prepared via solid die-drawing (SDD) at 135 °C. The results show that after SDD, on the existence of β-α phase transformation in processing, the toughness of PP/TMB-5...
