Sažetak
Supermolecular structure of isotactic polypropylene/wollastonite/metallocene propylene-ethylene copolymers (iPP/W/EPR) composites was studied as a function of elastomer content (from 0 to 20 vol. %) by optical, scanning and transmission electron microscopy, wide-angle X-ray diffraction and differential scanning calorimetry. The both, wollastonite and dispersed EPR particles, homogeneously incorporated into the iPP matrix, affected final phase structure and morphology of the iPP/wollastonite/EPR composites. Wollastonite particles were orientated plane-parallel to the sample surface and hindered spherulite growth of the iPP matrix. EPRs enhanced plane-parallel orientation of wollastonite and simultaneously enhanced the spherulite and crystallite growth in the iPP matrix during the solidification of polymer melt. Ternary iPP/wollastonite/EPR composites exhibited significant prevalence of separated microphase morphology (over core-shell morphology) due to constitution similarity of P-E and iPP chains.
