Description
  • The work focuses on microfibrillar-phase formation in polymer blends during extrusion through a die with semihyperbolic-converging channel. For these purposes, three polyethylene/polypropylene blends with the mixing ratios (wt./wt.) 80/20, 70/30 and 60/40 were prepared. Final structure and properties of extruded blends were examined using electron microscopy, wide-angle X-ray scattering, differential scanning calorimetry and tensile testing. It is demonstrated that the formation of microfibrillar-phase morphology is achieved in all blends, independent of their mixing ratios. However, the structure and properties of these microfibrillar-phase composites are strongly influenced by mixing parameters.

  • Tato práce se zaměřuje na přípravu mikrofibrilární fáze ve směsi polymerů během vytlačování přes hlavu se semi-hyperbolickým sbíhavým kanálem. K tomuto účelu byly připraveny tři směsi polyetylenu s polypropylenem s poměrem (hm./hm.) 80/20, 70/30 a 60/40. Konečná struktura a vlastnosti vyltačených směsí byly studovány pomocí elektronového mikroskopu, širokoúhlé rentgenografie, diferenciální snímací kalorimetrie a tahových zkoušek. Jak se ukázalo, tvorby mikrofibrilární fáze bylo dosaženo ve všech směsích, nezávisle na jejich složení. Nicméně struktura a vlastnosti těchto mikrofibrilárních kompozitů je výrazně ovlivněna právě míchacími poměry. (cs)
