Abstract
Positron annihilation spectroscopy (PAS) was utilized to investigate the re lationship between the free-volume hole properties and miscibility of dynam ically vulcanized EPDM/PP blend. The results showed that the noncrystalline region of PP and EPDM in the blend was partially miscible and the miscibil ity of the blend became worse when the weight percent of EPDM was <50%. Thi s was also demonstrated by DMTA and mechanical properties of the blends wit h various compositions.
