| Popis: | The effects of different contents of two metallocene propylene-based m-EPR elastomers on structure, morphology, thermal and dynamic mechanical properties of the isotactic polypropylene/m-EPR blends were investigated. The both m-EPR copolymers have been built in iPP matrix as amorphous phase. However, the nucleation effect at lowest addition (2.5 vol%) and the solidification effect along with increased m-EPR's additions have caused changes of the crystallinity degree and the size of spherulites in the iPP matrix. Higher degree of miscibility/compatibility of the iPP/m-EPR2, with lower viscosity has been observed. Homogeneous dispersion of m-EPR particles as well as their radial distribution has been observed. |
