Relation between morphology and properties of high-impact polypropylene
Original language description
High impact polypropylene (hiPP) is composed from porous isotactic polypropylene (iPP) matrix and from soft ethylene propylene random copolymer (EPR = ethylene propylene rubber) built in the pores of this matrix. The knowledge of the morphology of hiPP and the distribution of the EPR domains in the polymer particle is very important because the main application properties of hiPP material such as toughness depend strongly on the size and distribution of EPR domains in the iPP matrix. This work focuses the mapping of the morphology of hiPP with the aid of Atomic Force Microscopy (AFM). We succeeded with high-resolution imaging of EPR distribution in the cross-section of a whole hiPP particle and demonstrated the non-homogeneous distribution of EPR. Theprincipal result of this contribution is the description and understanding of EPR rubber growth within the matrix of iPP, because the initial porosity of iPP matrix is much smaller than the final content of EPR rubber.
