摘要：

PP was used as matrix resin, polyolefin elastomer(POE) and polyolefin plastomer(POP) were used as filler to prepare POE/PP and POP/PP with different components. The results of the mechanical properties of the blending system show that POP is weaker than POE at the same content for reducing elastic modulus of PP and effects of toughening modification, however when the POP content is increased to 40%, its mechanical properties are similar to those with the POE content of 30%; the electrical conductivity and alternating current/direct current (AC/DC) breakdown strength show that POP can highly maintain the electrical properties of PP; by observing the microscopic morphologies of the blends, it is found that the dispersion of POE in PP is poor, and POP at less monomer content shows less damage to the crystal regularity of PP, and the similar molecular structure of POP shows better compatibility with PP, which is the reason for the superior electrical properties, representing potential engineering application value. © 2020, Editorial Board of Polymer Materials Science & Engineering.
